Nigel Farage has resigned as the leader of the UK Independence Party, saying he has "done his bit".
Mr Farage said his aim in politics had been to get Britain out of the EU and now that the country had voted for Brexit in the referendum it was time for him to stand aside.
Douglas Carswell has told ITV News he will not stand to replace Nigel Farage as Ukip leader.
Asked whether he wanted to succeed Farage, Ukip's only member of Parliament replied: "Absolutely not - I couldn't possibly be a constituency MP, represent Ukip in the House of Commons, be a dad and lead a party."
Carswell, who has been locked in a feud with Farage, earlier tweeted a smiling emoji as news of the leader's decision to quit emerged.
Carswell admitted he and Farage had suffered "profound differences in opinion" over how the party should operate.
But he paid tribute to his former boss' role in convincing Britain to vote to leave the EU.
"For 20 years, Nigel stood at times almost alone in pushing for this referendum...we got the referendum and we won. Nigel played a key role in that and I think we should pay tribute to him."
