British Prime Minister Theresa May dug in against a growing push by both rivals and former allies to remove her from office as her attempts to lead Britain out of the European Union appeared to be headed for a dead end.
May resisted calls to rip up her tattered Brexit blueprint and end her embattled leadership after her attempt at compromise was rejected by both her own Conservative Party and opposition MPs.
Andrea Leadsom became the 36th ministerial resignation under May's watch when the Leader of the House of Commons said in a letter to the PM: "I no longer believe that our approach will deliver on the referendum result".
There was a feverish mood as rumours and plots swirled through Parliament, but Conservative MPs shied away from an immediate move against May.
Instead, they set up a meeting at the weekend between the Prime Minister and Graham Brady, the backbench MPs' elected chief, to discuss her future. Expectations are that she will be forced to announce her departure within days.
MP Tom Tugendhat, a leading Conservative moderate, said the only chance of delivering an orderly Brexit was for May "to go — and without delay".
"She must announce her resignation after [the] European elections. And the Conservative Party must fast track the leadership process to replace her," he wrote in the Financial Times.
Several senior ministers were reportedly seeking meetings with May to express unhappiness with her Brexit plan — and possibly urge her to quit. But her spokesman, James Slack, said he was "not aware of any discussions" with Cabinet colleagues.
In the House of Commons, May received a flurry of criticism and hostile questions as she implored MPs to support a bill implementing Britain's departure from the EU that she plans to put to a vote in Parliament in June.
Nearly three years after British voters opted to leave the EU, May said "we need to see Brexit through, to honour the result of the referendum and to deliver the change the British people so clearly demanded."
If Parliament rejected her deal, she said, "all we have before us is division and deadlock."
That could serve as a fair summary of Britain's current situation.
MPs have already rejected May's divorce deal with the 27 other EU countries on three occasions, and Britain's long-scheduled departure date of March 29 passed with the country still in the bloc.
In a last-ditch bid to secure support for her Brexit plan, May this week announced concessions including a promise to give Parliament a vote on whether to hold a new referendum on Britain's EU membership — something she has long ruled out.
"I have compromised. Now I ask you to compromise too," she said.
But there was little sign her plea was being heeded. Pro-EU and pro-Brexit MPs have only hardened their positions during months of political trench warfare, and they are in no mood to compromise.
Pro-Brexit Conservatives accused May of capitulating to pro-EU demands, and opposition Labour Party MPs dismissed her offer as too little, too late.
"The rhetoric may have changed but the deal has not," said Labour leader Jeremy Corbyn.
"She did not seek a compromise until after she had missed her own deadline to leave, and by the time she finally did, she had lost the authority to deliver."
May's authority as Conservative leader has been shredded by her loss of the party's parliamentary majority in a 2017 election and her failure to lead Britain out of the EU as promised.
The party's powerful anti-EU wing wants to oust May and replace her with a staunch Brexit supporter such as Boris Johnson, a former foreign secretary.
May has said she will announce a timetable for her departure once Parliament has voted on her Brexit bill. But with defeat of that bill looking highly likely, many in the party are pressing her to cancel the vote and quit even sooner.
May survived a no-confidence vote among Conservative MPs in December, leaving her safe from challenge for 12 months under party rules.
Brexit-backing MP Nigel Evans said he would urge the party's 1922 Committee, which oversees leadership contests, to change the rules when so that May can face a new challenge within days.
"Let's have somebody who has a clean sheet and will be able to reboot the (Brexit) negotiations," he said.
But the party committee decided instead to send Brady, its chairman, to meet May on Saturday NZT.
"I can't tell you what will be decided," said Steve Baker, a leading Conservative Brexiteer.
"People are rather impatient, but equally most colleagues do appreciate this is a very difficult time," he said.
Pressure on May is likely to increase when results come in from this week's elections for the European Parliament, with Conservatives expect to receive a drubbing.
Many British voters on both sides of the Brexit debate look set to use the election to the EU legislature to express displeasure over the political gridlock.
Opinion polls show strong support for the single-issue Brexit Party — largely from angry former Conservative voters — and for pro-EU parties including the Liberal Democrats and the Greens.
The election is being held tonight NZT in Britain, but results won't be announced until all 28 EU countries have finished voting late on Monday.
May indicated she would try to fight on. She said the Brexit withdrawal bill would be published so that MPs can study it.
Despite speculation that May will scrap plans to bring it to a vote to avoid a crushing defeat, her office said a vote will be held during the week of June 3.
"In time, another prime minister will be standing at this despatch box," May told lawmakers, acknowledging that her days in the job are numbered.
But, she told Parliament, "in the end our job in this House is to take decisions, not to duck them.
