UKIP's only MP Douglas Carswell quits the party

Douglas Carswell, UKIP's prominent MP, has left the party, leaving it without representation in Parliament. He previously won a byelection by a landslide after joining UKIP, but now plans to continue as an independent. UKIP faces challenges with Brexit negotiations under Theresa May, as their prospects for winning seats diminish. The party aims to ensure Brexit is fully realized, despite Carswell's secure position until the next election.
