Hundreds demonstrate against Theresa May's alliance with the DUP

But her party is deeply divided over what it wants from Brexit, and the election result means British businesses still have no idea what trading rules they can expect in the coming years.

British Foreign Secretary Boris Johnson has denied plotting to topple Prime Minister Theresa May, who has been weakened by the Conservative Party's disastrous election result.

At one of its most important moments in its history, the country is rudderless and facing a constitutional crisis.

On keeping Britain in the single market and customs union, he said: 'Well, the single market is a requirement of membership and since we won't be members there will have to be an arrangement.' Pressed if he was clear that the United Kingdom will leave the EU, he said: 'Absolutely.

May also said she would be meeting with her cabinet on Monday and going to France on Tuesday for meetings with French President Macron. Her failure to secure a working majority - falling below the 326 threshold by eight seats - led to talks with the DUP whose 10 seats will enable the party to push through Brexit legislation.

"The people of Britain have had a bellyful of promises and politicking", he wrote.

"I can still be prime minister", Corbyn tells the Sunday Mirror. May had called the election to build upon her majority; instead, the party lost it.

Theresa May will stay as on as the Prime Minister with support from the Democratic Unionist Party in defiance of critics both within and outside her own party, but it remains to be seen as she could continue to lead the party and the government in the long term.

Over the weekend, May's top two aides stepped aside.

The pair formed part of May's small inner circle and were blamed by many Conservatives for the party's lackluster campaign and unpopular election platform.

Michael Gove has been appointed Secretary of State for Environment, Food and Rural Affairs. "It's just how long she's going to remain on death row", former Conservative finance minister George Osborne, who was sacked by May when she became prime minister a year ago, told the BBC.

May called the vote three years early in the hope of scoring a sweeping win to strengthen her hand in the challenging Brexit talks, which are due to start in nine days' time.

David Davis, the cabinet member in charge of Brexit, said talks with the European Union may not start on Monday because it would clash with the Queen's Speech, but they will still begin next week.

"I felt sending people rude text messages was unacceptable".

Davis also suggested the government would focus on the divorce proceedings before moving on to trade.

There are also concerns about the potential impact of the proposed arrangement on Northern Ireland's peace agreement, which relies in part on London being an impartial arbiter between those, such as the DUP, who want the province to remain in the United Kingdom and those who want it to be part of Ireland.

Anand Menon, professor of politics at King's College London, said her lack of a parliamentary majority made it far more likely that Britain would leave the European Union without a deal.

The Times of London said in an editorial that "the election appears to have been, among other things, a rejection of the vague but harshly worded prospectus for Brexit for which Mrs".

Fallon told the BBC the government would be able to muster parliamentary support for its Brexit plans, adding: "Our view of Brexit I don't think has changed". "May would not have countenanced previously, and which would be positive".

A stream of senior lawmakers entered her office at 10 Downing St. on Sunday afternoon, to learn what roles they had been given in government. The Institute of Directors survey said company directors see no clear way to resolve the political situation quickly.
