Newcastle-under-Lyme is a constituency in northern Staffordshire created in 1354 and represented in the House of Commons of the UK Parliament since 2019 by Aaron Bell of the Conservative Party. It was the last to be co-represented by a member of the Conservative Party when it was dual-member, before the 1885 general election which followed the Redistribution of Seats Act 1885 coupled with the Reform Act 1884. In 1919 the local MP, Josiah Wedgwood, shifted his allegiance from the Liberal Party — the Lloyd George Coalition Liberals allying with the Conservatives — to the Labour Party and the seat elected the Labour candidate who has stood at each election for the next hundred years, a total of 29 elections in succession. Labour came close to losing the seat in 1969, 1986, 2015 and 2017, and eventually lost the seat in 2019.
