The Liberal Democrats attained their highest numerical majority in 1997 in Cornwall North East, which was won by Paul Tyler with a majority of 13,847 votes.
Mr Tyler captured the seat from the Conservatives in 1992, after a gap of over 17 years since he had last been an MP. He had previously held the neighbouring seat of Bodmin (now Cornwall South East) between the February and October 1974 elections.
The constituency is large with a long coastline stretching from the holiday resort of Newquay, through Padstow, Wadebridge, Tintagel and Bude right up to the border with Devon West and Torridge. It also reaches inland to Launceston in the east and Bodmin in the west. The main industries are agriculture and tourism.
Newquay is one of the most popular resorts in the British Isles with about 1 million visitors each year. It has an airport which has recently been redeveloped to attract more holiday flights.
Other resorts include Bude and Padstow, which has been made more popular by the chef Rick Stein. Most of the coastline and Bodmin Moor is designated as an area of outstanding natural beauty.
