The risk of Eurosceptic support being divided was shown as Jane Dodds, the Liberal Democrat candidate won the Brecon and Radnorshire by-election. Remain-supporting parties including the Greens, Plaid Cymru, Change UK and the Renew Party, stood aside and supported Ms Dodds. The combined Tory-Brexit vote exceeded the vote of Ms Dodds, and was only 350 votes behind the tally of Ms Dodds combined with fourth-placed Labour, fifth-placed Monster Raving Loony and sixth-placed Ukip.
Calls for the Brexit Party to stand aside in the seats of firm Tory Brexiteers and for the Tories to do the same in the traditional Labour heartlands in northern England.
As reported by Mail Online, Tory MPs have told Mr Farage he has a choice of delivering Brexit or destroying the Tories as he cannot do both.
Mr Farage tweeted: “As Claire Fox says, it is arrogant for the Conservatives to say we should stand aside. They are the very reason we exist. We simply do not trust them to deliver.”
Deputy Chairman of the European Research Group, Wycombe MP Steve Baker said: “It is becoming obvious to all now that the Brexit Party standing against the Conservative Party would produce a massive own goal.”

Crispin Blunt, a former Tory minister, said: “Are they really interested in Brexit, or are they interested in damaging the Conservative Party?”
Reports have claimed Boris Johnson’s special advisor Dominic Cummings is already drawing up plans for a campaign which would be spun as a fight between the people and the establishment.
A poll conducted by Ipsos MORI last week found the two parties would have a combined 43 percent of the vote in potential snap election.
The Electoral Calculus website suggested this would result in a massive 268 seat majority in the Commons.
The largest majority not formed by a coalition was the 225 seat Whig majority by Earl Grey in the 1832 election.
A 268 majority was only bettered by a 492 seat majority in 1931 for the national government led by Labour’s Ramsay MacDonald and the 609 seat majority gained by Stanley Baldwin leading a similar coalition four years later.
Perceived failures of previous coalition governments meant these unions were not formally described as coalitions.
Following the Brecon and Radnorshire defeat, Mr Johnson’s working majority is just one seat.
