LONDON (AP) -- British Prime Minister Theresa May was under pressure Wednesday to scrap a planned vote on her Brexit blueprint — and to resign — after her attempt at compromise got the thumbs-down from both her own Conservative Party and opposition lawmakers.
May plans to ask Parliament to vote next month on a bill implementing Britain's departure from the European Union.
Lawmakers have already rejected May's divorce deal with the EU three times, and Britain's long-scheduled departure date of March 29 passed with the country still in the 28-nation bloc.
In a last-ditch bid to secure support for her Brexit plan, May on Tuesday announced concessions including a promise to give Parliament a vote on whether to hold a new referendum on Britain's EU membership.
But opposition Labour Party lawmakers dismissed the offer as too little too late, and pro-Brexit Conservatives accused her of capitulating to pro-EU demands.
May faces a torrid session of criticism from all sides when she defends her Brexit deal in the House of Commons on Wednesday.
Labour Brexit spokesman Keir Starmer said May should reconsider and come back with a better offer that promised a "close economic relationship" with the EU and a new referendum.
"The prime minister needs to, today, accept that what she announced yesterday isn't going to work and pull the vote," Starmer told the BBC.
Conservative lawmakers, meanwhile, were due to meet later Wednesday to discuss whether to attempt to topple May as party leader.
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 likely, a growing number of Conservatives is pressing her to cancel the vote and quit even sooner.
Environment Secretary Michael Gove would not confirm that the bill would definitely be put to a vote the week of June 3, as May has promised.
"We will reflect over the course of the next few days on how people look at the proposition that has been put forward," he said.
