LONDON (AFP) -- British Prime Minister Theresa May took the blame for the ruling Conservatives’ disastrous performance at last week’s elections, as she faced her party’s angry MPs on Monday, seeking to ward off any challenge to her leadership.

“I got us into this mess and I’m going to get us out,” May told Conservatives MPs during the meeting in Westminster.

May’s Conservatives unexpectedly lost their majority in parliament in Thursday’s snap general election, causing political chaos ahead of Brexit talks with the European Union set to start next week and prompting calls -- from within her own party -- for her resignation.

But one MP present at the meeting said there was no discussion of a leadership contest, adding “she’s won, she’s got to be prime minister.”

The chaos has also weighed on the pound, which has plunged almost 2 percent since Thursday, and the government may have to delay the announcement of its policy plans to parliament.

May vowed to stay on despite the poor results, and on Sunday unveiled a largely unchanged new cabinet, which met for the first time Monday.

The Conservative Party fell eight seats short of retaining its parliamentary majority, and is now in talks with Northern Ireland’s ultraconservative Democratic Unionist Party -- which won 10 seats -- to forge an informal alliance.

DUP leader Arlene Foster is due to meet May on Tuesday for crunch talks, which could force the delay of the government’s presentation of its legislative program to parliament by Queen Elizabeth II, due Monday.

“Obviously until we have that we can’t agree the final details of the Queen’s Speech,” said May’s deputy Damian Green, referring to an agreement with the DUP.

Brexit Minister David Davis insisted the government still aimed to take Britain out of the EU single market in order “to take back control of our borders.”

He also told BBC radio that the government would “walk away” without a deal if the talks break down on ending Britain’s four-decade membership of the European bloc.

But Ruth Davidson, the pro-EU leader of the Conservatives in Scotland, called on May to “reopen” the government‘s Brexit plans.

Scottish First Minister Nicola Sturgeon said May’s government lacked the credibility necessary for Brexit talks and should delay the negotiations.

And according to The Daily Telegraph, some of the most senior members of May’s team have held “secret talks” with members of the opposition Labour Party to ensure a soft Brexit.

They hope to force May to make concessions on immigration, the customs union and the single market, the newspaper reported Tuesday.

May has a busy schedule Tuesday, hosting a cabinet meeting and talks with the DUP leader before traveling to Paris to meet French President Emmanuel Macron.

Brexit will likely be on the agenda at the Paris meeting, after May confirmed she will stick to the negotiating timetable.

“Going abroad and being seen to be the prime minister and talking to the president of France ... is a classic move to shore up authority at home,” said Colin Talbot, professor of government at the University of Manchester.

May tried to reassert her shattered authority at the weekend by announcing her new cabinet -- with no changes among her top team.

In a surprise move, Michael Gove was appointed environment and agriculture minister less than a year after the prime minister sacked him as justice minister.

After the Labour party made hefty electoral gains by focusing heavily on social issues, May listed areas such as education and housing as top policy priorities.

May has shown little public contrition for her electoral gamble that backfired spectacularly, but was forced to accept the resignations of her two top aides -- reportedly a requirement by cabinet colleagues for allowing her to stay in office.

DUP leader Foster said there had been “positive engagement” so far.

“We are going into these talks with the national interest at heart. The union as I’ve said before is our guiding star,” she said.

Defense Secretary Michael Fallon said the government was not looking at a formal coalition but would seek assurances that the DUP would vote with May “on the big things.”

He stressed he did not share their ultraconservative views on issues such as abortion and homosexuality, which have caused disquiet among many Conservatives.

The deal has also caused consternation in Dublin, with Irish Premier Enda Kenny warning such an alliance could upset Northern Ireland’s fragile peace.

London’s neutrality is key to the delicate balance of power in Northern Ireland, which was once plagued by violence over Britain’s control of the province.
