A new anti-Brexit political party launched its campaign Tuesday for next month's European elections as British lawmakers returned from their Easter break amid rumours of fresh bids to topple Prime Minister Theresa May.
The government and the main opposition Labour Party are also set to resume talks later Tuesday in an attempt to find agreement over Brexit after weeks of negotiations showed little signs of progress.
Britain is mired in a deep political crisis over its departure from the European Union, three years after a divisive referendum that voted to pull Britain out of the bloc after nearly half a century.
She is still hoping to persuade Labour to support the plan so the country can leave in time to avoid taking part in the European Parliament elections on May 23.
But with one month to go, few are expecting a consensus to emerge and Britain's political parties old and new are scrambling to organise for the upcoming polls.
Change UK, formed by breakaway MPs from Britain's two main parties disgruntled at their stances on Brexit, unveiled a roster of candidates at an event in Bristol in southwest England.
The list includes former Polish deputy prime minister Jan Vincent Rostowski and prominent columnist Rachel Johnson -- the sister of former foreign minister and leading Brexiteer Boris Johnson.
Rachel Johnson told London's Evening Standard newspaper she felt "impelled to stand up and be counted for what I believe in".
Interim party leader Heidi Allen, who quit the Conservatives in February, said it had received 3,700 candidate applications, many from former Labour, Tory, Liberal Democrat and Green activists.
"This is the home of the Remain alliance," she said, adding the elections are a chance to reiterate the need for a second referendum on Brexit.
Anti-EU firebrand Nigel Farage launched his new Brexit Party's campaign earlier this month, with Annunziata Rees-Mogg -- the sister of leading Tory eurosceptic Jacob Rees-Mogg -- one of its candidates.
The former UK Independence Party (UKIP) leader, who led that party to first place the last time Britain held European elections in 2014, has seen his new grouping surge in the polls since the launch.
It also announced on Tuesday five more candidates, which include Claire Fox, a left-wing libertarian and regular TV pundit as it targets traditional, Brexit-leaning Labour constituencies.
May's Conservative Party is watching nervously, with grassroots members and local leaders fearing a wipe-out amid voter discontent over her handling of Brexit. Her unpopular withdrawal deal reached with the EU has already been rejected three times by parliament, and is unpopular with party members.
But May could bring it back before MPs again as early as next week in a high-stakes gamble to avoid holding the European elections, according to the Guardian. MPs are agitating for the prime minister, who has agreed to resign once the first phase of the exit process is finished, to make way for a new leader now.
Nigel Evans, a senior member of the powerful 1922 Committee of Tory MPs, told the BBC on Tuesday he would be "delighted" if she announced her resignation immediately.
"I believe the only way we're going to break this impasse properly is if we have fresh leadership," he said.
May could face another vote of confidence from her own MPs if they agree at a meeting on Tuesday to change the rules that currently prevent a leader from facing two such votes in a one-year period.
She survived a vote of confidence in December but grassroots discontent could increase pressure on the 1922 Committee to allow another vote at a sooner date, with reports suggesting June.
"It's something that's got to be done and the longer you leave it the worse it will be.
