Somerset and North Devon was a European Parliament constituency covering all of Somerset in England, plus northern Devon and south-western Avon. With Cornwall and West Plymouth, it was one of the first two seats to elect a Liberal Democrat Member of the European Parliament. The constituency consisted of the Westminster Parliament constituencies of Bridgwater, North Devon, Somerton and Frome, Taunton, Wells, Weston-super-Mare and Yeovil. The constituency replaced most of Somerset and West Dorset and parts of Devon. It became part of the much larger South West England constituency in 1999.
