Foreign Secretary Dominic Raab has warned Tory MPs and former members of the party not to back Jeremy Corbyn as a means of blocking a no-deal Brexit.
Mr Raab told his party conference in Manchester that “history would never forgive” them if they helped the Labour leader form an interim government.
The warning came after the SNP’s Westminster leader Ian Blackford used a Sunday Times column to urge MPs to bury the hatchet and remove Boris Johnson from office to prevent a no-deal.
Mr Raab said: “I say this as a passionate Brexiteer, there are some things even bigger than Brexit – and keeping that lot out of Downing Street is one of them.
“So, to any of our colleagues – or former colleagues – who may just be tempted to put Jeremy Corbyn and that Momentum mob into No 10 as part of some temporary anti-Brexit coalition, I just say this: history will never forgive you.”
Mr Raab also attacked the Liberal Democrats for making it policy to cancel the referendum result.
He said: “They want to scrap the result of the 2016 vote. You can’t call yourself a democrat, put it in the name of your party and then try to cancel a referendum.
“This prime minister is offering a better way forward. Let’s get Brexit done, let’s move on, let’s unite behind our One Nation vision for the country, and let’s bring the Conservative family back together.
“We in the Conservative party keep our promises. We’re going to make a success of Brexit, and we will free our country to reach its full potential.”
