Information:  - The River Thames is a river that flows through southern England. At , it is the longest river entirely in England and the second longest in the United Kingdom, after the River Severn. It also flows through Oxford (where it is called Isis), Reading, Henley-on-Thames and Windsor. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. It rises at Thames Head in Gloucestershire, and flows into the North Sea via the Thames Estuary. The Thames drains the whole of Greater London.   - The Parliament of the United Kingdom, commonly known as the UK Parliament or British Parliament, is the supreme legislative body in the United Kingdom, British Crown dependencies and British overseas territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Its head is the Sovereign of the United Kingdom (currently Queen Elizabeth II) and its seat is the Palace of Westminster in the City of Westminster, London.  - The Palace of Westminster is the meeting place of the House of Commons and the House of Lords, the two houses of the Parliament of the United Kingdom. Commonly known as the Houses of Parliament after its occupants, it is also known as the 'heart of British politics'. The Palace lies on the north bank of the River Thames in the City of Westminster, in central London.  - Middlesex (abbreviation: Middx) was a county in southeast England that is now mostly part of Greater London, with small sections in neighbouring counties. It was established in the Anglo-Saxon system from the territory of the Middle Saxons, and existed as an official unit until 1965. The historic county included land stretching north of the River Thames from east to west of the City of London with the rivers Colne and Lea and a ridge of hills as the other boundaries. The largely low-lying county, dominated by clay in its north and alluvium on gravel in its south, was the second smallest by area in 1831.  - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.  - The Parliament of England was the legislature of the Kingdom of England. In 1066, William of Normandy introduced what, in later centuries, became referred to as a feudal system, by which he sought the advice of a council of tenants-in-chief (a person who held land) and ecclesiastics before making laws. In 1215, the tenants-in-chief secured Magna Carta from King John, which established that the king may not levy or collect any taxes (except the feudal taxes to which they were hitherto accustomed), save with the consent of his royal council, which gradually developed into a parliament.  - Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the ' (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President, and appoints other government ministers.  - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - The charter became part of English political life and was typically renewed by each monarch in turn, although as time went by and the fledgling English Parliament passed new laws, it lost some of its practical significance. At the end of the 16th century there was an upsurge in interest in Magna Carta. Lawyers and historians at the time believed that there was an ancient English constitution, going back to the days of the Anglo-Saxons, that protected individual English freedoms. They argued that the Norman invasion of 1066 had overthrown these rights, and that Magna Carta had been a popular attempt to restore them, making the charter an essential foundation for the contemporary powers of Parliament and legal principles such as "habeas corpus". Although this historical account was badly flawed, jurists such as Sir Edward Coke used Magna Carta extensively in the early 17th century, arguing against the divine right of kings propounded by the Stuart monarchs. Both James I and his son Charles I attempted to suppress the discussion of Magna Carta, until the issue was curtailed by the English Civil War of the 1640s and the execution of Charles. The political myth of Magna Carta and its protection of ancient personal liberties persisted after the Glorious Revolution of 1688 until well into the 19th century. It influenced the early American colonists in the Thirteen Colonies and the formation of the American Constitution in 1787, which became the supreme law of the land in the new republic of the United States. Research by Victorian historians showed that the original 1215 charter had concerned the medieval relationship between the monarch and the barons, rather than the rights of ordinary people, but the charter remained a powerful, iconic document, even after almost all of its content was repealed from the statute books in the 19th and 20th centuries.  - The Celtic Sea (; ) is the area of the Atlantic Ocean off the south coast of Ireland bounded to the east by Saint George's Channel; other limits include the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, Devon, and Brittany. The southern and western boundaries are delimited by the continental shelf, which drops away sharply. The Isles of Scilly are an archipelago of small islands in the sea.  - The 14 British Overseas Territories (BOT) are territories under the jurisdiction and sovereignty of the United Kingdom. They are those parts of the former British Empire that have not chosen independence or have voted to remain British territories. Most of the inhabited territories are internally self-governing, with the UK retaining responsibility for defence and foreign relations. The rest are either uninhabited or have a transitory population of military or scientific personnel. They share the British monarch (Elizabeth II) as head of state.  - Northern Ireland (; Ulster Scots: "") is a top-level constituent unit of the United Kingdom in the northeast of Ireland. It is variously described as a country, province, region, or "part" of the United Kingdom, amongst other terms. Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in some areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments".  - The Parliament of Scotland, officially the Estates of Parliament, was the legislature of the Kingdom of Scotland. The parliament, like other such institutions, evolved during the Middle Ages from the king's council of bishops and earls. It is first identifiable as a parliament in 1235, during the reign of Alexander II, when it was described as a "colloquium" and already possessed a political and judicial role. By the early fourteenth century, the attendance of knights and freeholders had become important, and from 1326 commissioners from the burghs attended. Consisting of the "three estates" of clergy, nobility and the burghs sitting in a single chamber, the parliament gave consent for the raising of taxation and played an important role in the administration of justice, foreign policy, war, and all manner of other legislation. Parliamentary business was also carried out by "sister" institutions, such as General Councils or Convention of Estates. These could carry out much business also dealt with by parliament  taxation, legislation and policy-making  but lacked the ultimate authority of a full parliament.  - The Kingdom of Great Britain, officially Great Britain , was a sovereign state in western Europe from 1 May 1707 to 31 December 1800. The state came into being following the Treaty of Union in 1706, ratified by the Acts of Union 1707, which united the kingdoms of England and Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands. It did not include Ireland, which remained a separate realm. The unitary state was governed by a single parliament and government that was based in Westminster. The former kingdoms had been in personal union since James VI, King of Scots, became King of England and King of Ireland in 1603 following the death of Queen Elizabeth I, bringing about a "Union of the Crowns". Also after the accession of George I to the throne of Great Britain in 1714, the kingdom was in a personal union with the Electorate of Hanover.  - Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago.  - The Kingdom of England was a sovereign state on the island of Great Britain from the 10th centurywhen it emerged from various Anglo-Saxon kingdomsuntil 1707, when it united with Scotland to form the Kingdom of Great Britain.  - Middlesex is a former United Kingdom Parliamentary constituency . It was a constituency of the House of Commons of the Parliament of England , then of the Parliament of Great Britain from 1707 to 1800 , and finally of the Parliament of the United Kingdom from 1801 to 1885 .  - Ireland (Ulster-Scots: ) is an island in the North Atlantic. It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest on Earth.  - The Irish Sea (, , , Ulster-Scots: "Airish Sea"), separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea.  - The Acts of Union 1800 (sometimes erroneously referred to as a single Act of Union 1801) united the Kingdom of Great Britain and the Kingdom of Ireland (previously in personal union) to create the United Kingdom of Great Britain and Ireland with effect from 1 January 1801. Both Acts, though since amended, still remain in force in the United Kingdom, but have been repealed in the Republic of Ireland.  - The Parliament of Great Britain was formed in 1707 following the ratification of the Acts of Union by both the Parliament of England and the Parliament of Scotland. The Acts created a new unified Kingdom of Great Britain and dissolved the separate English and Scottish parliaments in favour of a single parliament, located in the former home of the English parliament in the Palace of Westminster, near the City of London. This lasted nearly a century, until the Acts of Union 1800 merged the separate British and Irish Parliaments into a single Parliament of the United Kingdom with effect from 1 January 1801.  - The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World".  - The English Channel ("the Sleeve" [hence ] "Sea of Brittany" "British Sea"), also called simply the Channel, is the body of water that separates southern England from northern France, and joins the southern part of the North Sea to the rest of the Atlantic Ocean.  - The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, with an area of around .  - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency.  - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly.  - The Middle Saxons or Middel Seaxe were a people whose territory later became, with somewhat contracted boundaries, the county of Middlesex, England. It included the early London settlement, and probably Surrey, the "south region" of the Middle Saxon territory.
