The constituency is the north-western part of the Cheshire East unitary authority, including the towns of Knutsford and Wilmslow, and a number of villages such as Alderley Edge, Chelford, Handforth and Mobberley, in Cheshire. It also covers a small, north-east, part of the Cheshire West and Chester unitary authority, including some of the outskirts of Northwich.
The constituency is named after Tatton Park, a stately home in this area.
The constituency was created in 1983 from parts of the seats of Runcorn, Cheadle, Northwich and Knutsford. It was held by the Conservative Neil Hamilton until 1997.
Tatton shot to fame during the 1997 general election campaign, becoming one of the highest-profile constituencies at that election. Following Hamilton's implication in the Cash for Questions scandal of the 1990s, the Labour Party and the Liberal Democrats withdrew their candidates in favour of the former BBC journalist Martin Bell, who stood as an Independent, while those two parties supported his "anti-corruption" campaign. Bell was ultimately victorious, with a majority of over 11,000 over Hamilton.
Bell did not contest the seat at the 2001 election, and the seat was won by Conservative George Osborne with a majority of 8,611 (20.8%).Prominent members of the frontbenches
Osborne held the seat at the 2005 election with an increased majority, and became the Shadow Chancellor that year. He held the position of Chancellor of the Exchequer from 2010 to 2016, one of the highest frontbench government positions.
Tatton includes Alderley Edge, Wilmslow and other outlying villages which have high property prices. The seat largely comprises prosperous villages and small towns set amidst Cheshire countryside, featuring country parks, hills, recreation grounds and golf courses, previously dominated by countryside however since the 1950s, with a largely built-up, suburban character, on the fringes of Greater Manchester. The largest centres of population are Alderley Edge, Wilmslow and Knutsford. Its proximity to Manchester means Tatton forms part of the commuter belt to the city.
Workless claimants, registered jobseekers, were in November 2012 lower than the national average of 3.8%, at 2.1% of the population based on a statistical compilation by The Guardian.
During the 2016 EU Referendum, the constituency voted to remain in the EU, despite both Cheshire East and Cheshire West and Chester voting to leave overall. The margin was 55.56% Remain over 44.44% Leave.
