Please answer the following question: Information:  - Eastbourne is a large town, seaside resort and borough in the non-metropolitan county of East Sussex on the south coast of England, east of Brighton. Eastbourne is immediately to the east of Beachy Head, the highest chalk sea cliff in Great Britain. With a seafront consisting largely of Victorian hotels, a pier and a Napoleonic era fort and military museum, Eastbourne was developed by the Duke of Devonshire from 1859 from four separate hamlets. It has a growing population, a broad economic base and is home to companies in a wide range of industries.  - Alfriston is a village and civil parish in the Sussex district of Wealden , England . The village lies in the valley of the River Cuckmere , about four miles ( 6 km ) north - east of Seaford and south of the main A27 trunk road and part of the large area of Polegate . The parish has a population of 769 ( 2001 census ) , increasing to 829 at the 2011 census .  - Polegate is a town and civil parish in the Wealden District of East Sussex, England, United Kingdom. It is located five miles (8 km) north of the seaside resort of Eastbourne, and is part of the greater area of that town. Although once a railway settlement, its importance as such has now waned with closures of routes. The parish of Polegate had a population of 8586 on the 2011 census of which 41.2% were aged 65 and over.  - A parish is a church territorial unit constituting a division within a diocese. A parish is under the pastoral care and clerical jurisdiction of a parish priest, who might be assisted by one or more curates, and who operates from a parish church. Historically, a parish often covered the same geographical area as a manor (its association with the parish church remaining paramount).  - In England, a civil parish is a territorial designation which is the lowest tier of local government below districts and counties, or their combined form, the unitary authority. It is an administrative parish, in contrast to an ecclesiastical parish.  - The River Cuckmere rises near Heathfield in East Sussex, England on the southern slopes of the Weald. The name of the river probably comes from an Old English word meaning "fast-flowing", since it descends over 100 m (328 ft) in its initial four miles (6.4 km). It flows into the English Channel, and has the only undeveloped river mouth on the Sussex coast.  - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight.  - 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 Weald is an area in South East England situated between the parallel chalk escarpments of the North and the South Downs. It crosses the counties of Sussex, Hampshire, Kent and Surrey. It has three separate parts: the sandstone "High Weald" in the centre; the clay "Low Weald" periphery; and the Greensand Ridge, which stretches around the north and west of the Weald and includes its highest points. The Weald once was covered with forest, and its name, Old English in origin, signifies "woodland." The term is still used today, as scattered farms and villages sometimes refer to the Weald in their names.  - East Sussex is a county in South East England. It is bordered by the counties of Kent to the north and east, Surrey to the north west and West Sussex to the west, and to the south by the English Channel.  - A unitary authority is a type of local authority that has a single tier and is responsible for all local government functions within its area or performs additional functions which elsewhere in the relevant country are usually performed by national government or a higher level of sub-national government.  - Wealden is a local government district in East Sussex, England: its name comes from the Weald, the remnant forest which was once unbroken and occupies much of the centre and north of this area. The term is cognate with "Wald", forest or wood in German.    What entity does 'alfriston' has the relation 'located in the administrative territorial entity' with?
