LONDON: The anti-EU UK Independence Party needs a fresh face as leader, its only lawmaker said on Friday, highlighting divisions in a party which will play a key role in the campaign for Britain to leave the bloc at an upcoming membership referendum.

Prime Minister David Cameron promised that vote in part due to pressure from the rise in popularity of UKIP, which won 2014’s European elections in Britain and posed a threat to his Conservative Party ahead of May’s national election.

UKIP leader Nigel Farage, who casts himself as a man of the people, has helped turn UKIP from a fringe movement into a political force that came third in May with more than 12 percent of the vote.

But under Britain’s first-past-the-post electoral system it emerged with just one lawmaker and this month failed to make expected inroads in a vote for a parliamentary seat in Oldham in northern England.

“It is not for me to decide who the leader of the party is but I think it is fair to say that we all need to think very carefully as to whether or not we can build beyond the base that we have now got without that change,” UKIP lawmaker Douglas Carswell told the BBC in an interview broadcast on Friday.
