Both have warned they will lose their seats unless the Tories deliver Brexit.

Asked if Brexiteers needed to put the PM's future to a vote of the Conservative Party, he replied "it may well come to that".

Mr Paterson is considered influential, as a former minister who wants a hard Brexit. "Boris Johnson has been a friend of the president, was a friend during the election and he has a warm and close relationship with the president".

Theresa May has moved to shore up her position following the shock resignation of Boris Johnson with the appointment of Jeremy Hunt as the new Foreign Secretary.

Two Brexit disruptors, two very different resignations.

However, one high-profile county Conservative pulled no punches in his call for Mrs May to step down.

"It's regrettable it hasn't been resolved yet, I think there should be less hype and over spinning and let's focus on detailed negotiations. But the United Kingdom certainly has a lot of things going on", he said.

Nervousness over Mrs May's position has been compounded since Britain's relations with Europe have instrumental in the departures of the previous three British prime ministers from her party.

There are those who have been quick to say how they are glad to see the back of Davis and especially Johnson, arguing they have not been up to their jobs.

But leading pro-Brexit lawmaker Jacob Rees-Mogg said he didn't think she would face a leadership challenge.

European Union officials say they will respond to the proposals once they have seen details.

Margaret Thatcher initially supported the 1975 referendum on the U.K.'s European Union membership, but a string of firings and resignations of cabinet members (sound familiar?) who favored more integration against her wishes led to her downfall.

She told BBC Two's Newsnight: "I think if the Prime Minister makes further concessions with the European Union then there will no doubt be more resignations from Brexiteers in the Cabinet, from junior ministers to PPSs because there is only so much that you can give in a negotiation".

However, county MPs Daniel Kawczynski, Philip Dunne, Lucy Allan, Mark Pritchard and Montgomeryshire Conservative Glyn Davies have all urged their party colleagues to support the leader. However, the Environment Secretary later insisted he would not be leaving the Cabinet.

"They´ll keep going, one by one, until she either junks Chequers or goes", the MP was quoted as saying. "But there are people in Labour and the Liberal Democrats who wish to damage the sort of Brexit that many of my constituents have voted for".

Johnson may be warming up his vocal chords to sing a new Brexit song that does not stick in his throat.

"I have not, no, I have not", he said.

"I assume we'll continue to be promiscuous about these negotiations: we'll try everything with nearly everyone".

El Pais says "differences over Brexit break the British government".

Bookies are now putting Davidson at an average of 40/1 to be the next leader, but a recent YouGov survey of Tory members shows that she polls better in a number of fields than numerous other potential leaders.

The news has sparked speculation of a potential leadership challenge, and the threat of another general election.

In recent days, British politics has gone insane, and the prime minister, Theresa May, is in grievous peril of blowing her government to pieces.

Boris Johnson quit his post yesterday, following the earlier resignation of Brexit Secretary David Davis, putting the government in a tight spot with less than nine months left to complete the complex Brexit negotiations.

But even if she achieved that threshold, a narrow victory would seriously undermine her authority and may lead her to question whether it was worth carrying on. "David might just have saved the party, let's hope".
