The Lib Dem victory comes roughly a year after a similar result in the Tiverton and Honiton by-election, a similar southwest constituency.

David Warburton stood down as Somerton and Frome MP last month, shortly after it was found that an investigation into claims he sexually harassed someone was "materially flawed".

However the MP - who had been suspended from the Conservative Party in parliament - did admit to drug use.

His seat has now been taken over by the Lib Dems' Sarah Dyke with a majority of 11,008. The Tory candidate was Faye Purbrick.

Ms Dyke received 21,187 votes, while the Conservatives took 10,179, the Greens 3,944, Reform 1,303 and Labour 1,009.

This equates to a 29 point swing to the Liberal Democrats, and the Conservatives have never had a lower share of the vote in the seat.

Speaking after her win, Ms Dyke said: "Tonight has been a stunning and historic victory for the Liberal Democrats, and it shows once and for all, the Liberal Democrats are back in the West Country.

"Lifelong conservative voters have today voted Liberal Democrat for the first time. Thank you for putting your trust in me to deliver for you. I will not let you down."

Unlike Tiverton and Honiton, the Lib Dems have held Somerton and Frome in recent memory.

Mr Warburton only won the seat for the Conservatives in 2015 from the Lib Dems. Coalition minister David Heath had held it for 18 years previously but stepped down at the 2015 election, when David Cameron's Tories won an unexpected majority nationally.

Despite Lib Dem success in this seat in the past this election still required a sizeable shift in opinion from 2019, as the Conservatives had been sitting on a majority of more than 19,000.

The seat is largely older than average and has been less exposed to interest rate rises due to a lower number of mortgage-holders, with 43% of homes being owned without a loan. But the momentum had been swinging away from the Tories in the region.

The 2022 council elections saw sizeable falls in the Conservative wards in the region, with the Lib Dems claiming first place in 10 of 13 seats and taking 40% of the vote.

The Tories won just one ward; the other two were taken by the Greens.
