LONDON, United Kingdom - Prime Minister Theresa May set out a "new deal" on Tuesday for Britain's departure from the European Union, offering sweeteners to parliament including the chance to vote on whether to hold a second referendum to try to break the impasse over Brexit.
Three years after Britain voted to leave the EU and almost two months after the planned departure date, May is mounting a last effort to try to get the deeply divided parliament's backing for a divorce deal and leave office with some kind of legacy.
The odds do not look good.
May offered what she called "significant further changes" but many lawmakers, hardened in their positions, have already decided not to vote next month for the Withdrawal Agreement Bill, legislation that implements the terms of Britain's departure.
Speaking at the headquarters of PricewaterhouseCoopers, May appealed to lawmakers to get behind her deal, offering the prospect of a possible second referendum on the agreement and closer trading arrangements with the EU as incentives.
"I say with conviction to every MP or every party: I have compromised, now I ask you to compromise," she said.
"We have been given a clear instruction by the people we are supposed to represent, so help me find a way to honor that instruction, move our country and our politics and build the better future that all of us want to see."
By offering the possibility of holding a second vote on her deal and a compromise on customs arrangements, May hopes to win over opposition Labor lawmakers, whose votes she needs to overcome resistance in her own Conservative Party.
But Labor leader Jeremy Corbyn said his party could not vote for the Withdrawal Bill, describing May's new offer as "largely a rehash of the government's position" in talks with the opposition that broke down last week.
The prime minister has also infuriated Brexit-supporting lawmakers, who have described a customs union with the EU as no Brexit at all.
Several leading Conservative eurosceptics such as former Brexit minister David Davis and Jacob Rees-Mogg said they would not vote for the bill in early June.
Former foreign minister Boris Johnson and ex Brexit minister Dominic Raab, who are the top two favorite choices among Conservative members to replace May according to an opinion poll published last week, also said they would oppose the deal.
And Northern Ireland's Democratic Unionist Party, which props up May's government, said the "fatal flaws" of her original deal remained. They fear the divorce deal could see Northern Ireland split from the rest of the United Kingdom.
May's movement towards what many describe as the "Remain" lawmakers, who want to stay in the EU, is a shift for a prime minister who has long said she is against a second referendum and staying in a customs union with the bloc.
She may be counting on the fact that parliament - which would have to back any new referendum - has so far opposed any second public vote and also that a "temporary" customs union might just be weak enough for some in her party to accept.
But it signals how her earlier strategy, to keep Brexit supporters on board, has failed and the last-ditch attempt to get Labor lawmakers - if not their leader - behind her is simply too little, too late, some say.
"It's a gimmick from a desperate PM who has run out of road, refuses to compromise and for three years has sidelined parliament and the country," Labor lawmaker Seema Malhotra told Reuters.
Brexit-supporting Conservatives were equally unconvinced.
David Jones, a former minister, described the speech as "unacceptable" and predicted that the move just before Thursday's elections to the European Parliament would only buoy support for veteran eurosceptic Nigel Farage's Brexit Party.
"I believe more Conservatives will vote against it," he told Reuters. "Regrettably, it will probably also boost the Brexit Party vote on Thursday."
May wants to get her withdrawal deal, agreed with the EU last November, through parliament so she can leave office as promised having at least finalized the first part of Britain's departure and prevented a "no deal" Brexit.
The deal has been rejected three times by parliament but many businesses fear that the abrupt departure of an exit with no deal agreed would cause an economic shock.
Finance minister Philip Hammond rammed the point home in parliament on Tuesday, saying a no-deal Brexit would leave Britain poorer. He was expected to send the same message to business leaders in a speech later in the day.
"The 2016 Leave campaign was clear that we would leave with a deal," he was set to say, according to advance extracts.
"So to advocate for 'no deal' is to hijack the result of the referendum, and in doing so, knowingly to inflict damage on our economy and our living standards. Because all the preparation in the world will not avoid the consequences of no deal."
