In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides.  - The Judiciary of England and Wales contains many levels, based on the court in which the judge sits. Titles are given to judges relating to their position and, in the case of knighthoods and peerages, this includes the positions they had previously held. Retired judges that sit in any court use their full name with their titles added (such as Sir or Dame, or post-nominal QC).  - The office of sheriff principal is unique within the judicial structure of Scotland, and it cannot therefore readily be compared with any other judicial office. It is one of great antiquity, having existed continuously since around the 11th century. It has gradually developed over the centuries, and is still developing, into an office of some complexity and considerable weight.   - James Alastair Taylor ( born 21 February 1951 ) is Sheriff Principal of the Sheriffdom of Glasgow and Strathkelvin .  - A sheriff is a government official, with varying duties, existing in some countries with historical ties to England, where the office originated.
