The chair of Ukip's group for LGBT (lesbian, gay, bisexual and transgender) supporters has quit the party, citing "dissatisfaction at the failure of the leadership to set a gay-friendly tone".
Tom Booker had led the LGBT in Ukip group for three years, but said in a message on Twitter that he was giving up his membership because he found it "increasingly difficult" to defend the party's policies.
"Last night I stepped down as chairman of LGBT in Ukip and gave up my membership of #ukip. I'll remain unaffiliated...for now," said Mr Booker.
"I found that I couldn't defend the party or convincingly campaign for it any more. It became increasingly difficult for me to argue for a non-Classical Liberal manifesto."
Mr Booker later told PinkNews magazine: "I stepped down from my position as founder-chairman of LGBT in Ukip, and resigned my membership of Ukip, due to disillusionment of policy direction and dissatisfaction at the failure of the leadership to set a gay-friendly tone.
"I am proud of my contribution to Ukip. The new LGBT in Ukip committee is excellent, and I hope that the enthusiasm and dedication of the committee will take the group to new heights. I would like to wish them all the best."
Meanwhile, a poll commissioned by Ukip donor Alan Brown put Nigel Farage on course for a resounding win in the Kent seat he is contesting at the general election.
The party leader is on 39% in South Thanet, with Labour on 28% and the Conservatives on 27%, according to the Survation study.
:: Survation polled 1,011 adults in South Thanet by telephone from February 18-20.
