Douglas Carswell won the seat as a Conservative in 2010, resigned his seat in 2014, won it for UKIP in the resulting by-election, retained it in 2015 but lost to the Conservative in 2017. My feeling is that Clacton is Reform’s best chance of winning a seat and Farage’s profile will only increase that chance. I have no doubt that he is looking forward to the cheap beer, and the chance to grandstand, disrupt the Commons and raise his money-making profile. If Lindsay Hoyle suddenly decides to stand down, we will know why.
EDIT (for accuracy): Carswell did not lose the seat in 2017, but stood down.
