This is a largely rural seat with agriculture, bulb growing and food processing as the main economic activities.[3] Incomes and house prices are below UK averages.[4]
The last non-Conservative member for the predecessor main seat was Sir Herbert Butcher (served 1937–1966) who for much of that time was in the National Liberal Party set up in 1931.
In the 2017 general election, the seat returned the highest vote share for the Conservatives nationally at 69.9%.[6] In the 2019 general election, it was an extremely safe Conservative seat. It had the largest percentage majority, third-largest absolute majority, and third-largest Conservative vote share of any seat held by the party; nationally the seat had the eleventh-largest percentage majority of any constituency.[7]
