Nigel Farage has turned down an 11th-hour electoral pact offer from the Conservatives, according to reports.
Boris Johnson suggested the Tories could put up paper candidates in Labour held seats and do minimal campaigning.
This would give the Brexit Party a stronger chance of winning in Leave-supporting areas. But the deal was reportedly rejected by Mr Farage who wanted the Tories to step aside entirely in the constituencies.
He also feared it would leave the Brexit Party with just 40 target seats. The talks broke down on Tuesday and the deadline to nominate candidates arrives at 4pm today.
Mr Johnson’s final offer came after after the Brexit Party withdrew its own candidates from all 317 seats currently held by Conservatives, the Telegraph reports.
Mr Farage described this as the first step towards building a leave alliance. But the Brexit Party leader remains under pressure to withdraw even more candidates.
The Prime Minister has insisted voting Conservative is the only way to get Brexit done. Mr Farage has said he will field candidates in every Labour-held seat in a move that could hamper Tory efforts to win a majority.
A Brexit Party source said: At every election the Tories have upwards of 100 paper candidates.
