BERLIN: Embattled British Prime Minister Theresa May embarked on a tour of European capitals on Tuesday in a desperate bid to salvage her Brexit deal, a day after delaying a parliamentary vote on the text to avoid a crushing defeat.
May had breakfast with Dutch Prime Minister Mark Rutte in The Hague before heading to Berlin for lunch with Chancellor Angela Merkel, and was then to travel on to Brussels.
She is seeking "reassurances" over provisions in the EU withdrawal agreement concerning Northern Ireland, which she hopes could persuade her rebellious Conservative party to support it.
European Commission chief Jean-Claude Juncker said ahead of meeting May that he was "surprised" at being asked for more talks.
"I'm surprised because we had reached an agreement on November 25" at the last EU summit, he told the European Parliament in Strasbourg.
"The deal we have achieved is the best deal possible, it's the only deal possible.
"There is no room whatsoever for renegotiation but of course there is room if used intelligently, to give further clarification and further interpretations."
MPs in the House of Commons were due to vote on the deal on Tuesday night, but May deferred it on Monday, admitting she expected to lose by a "significant margin".
Her spokesman said Tuesday the vote would be rescheduled before January 21 -- just months before Britain leaves the EU on March 29.
EU President Donald Tusk, who was also to meet May in Brussels, has called a meeting of the other 27 EU leaders on Thursday to discuss the latest Brexit developments.
They and May were already due to attend a European Council summit on Thursday and Friday, which the British prime minister is expected to use to further press her case.
Irish Foreign Minister Simon Coveney said his government ruled out changes to the wording of the withdrawal agreement, but said there could be "a political declaration coming from a European Council".
"The Irish government doesn't have an issue with providing reassurance if that's helpful," he told national broadcaster RTE.
May faces strong opposition from her own Conservative MPs and parliamentary allies over a clause in the Brexit deal designed to keep open the border with Ireland.
The so-called backstop risks tying Britain into a customs union with the EU for years after it leaves the bloc -- far from the clean break that eurosceptics want.
"I have heard those concerns and I will now do everything I possibly can to secure further assurances," May told mutinous MPs on Monday, after pulling the vote.
But it is far from clear what she can achieve.
One of her ministers, Martin Callanan, said in Brussels on Tuesday that Britain is seeking "additional legal reassurances that UK cannot be permanently trapped in the Irish backstop".
The leader of the House Andrea Leadsom said this could take the form of "an addendum".
May said on Monday that "nothing should be off the table", but warned that reopening the withdrawal agreement could see other countries seek to remove bits they do not like, for example on fishing rights.
Anand Menon, European politics professor at King's College London, said May needed Brussels to make it "absolutely clear" that it would offer no new concessions on the deal.
"I imagine they'll add some language saying that both sides remain convinced that we'll never need to use the backstop," he told AFP.
Even if no deal is secured, Britain is still on course to leave the EU on March 29 -- a scenario the government has warned will be hugely damaging to the economy.
The decision to defer the vote sent the pound plunging.
Tusk said Thursday's EU meeting would cover no-deal plans, while May's cabinet was also due to discuss the issue on Wednesday.
France's minister for European affairs, Nathalie Loiseau, said the possibility of no deal was "not unlikely", adding: "I'm very worried."
May's decision also drew outrage from MPs, who demanded the right to vote on the Brexit deal.
Opposition Labour leader Jeremy Corbyn is facing calls to table a no-confidence vote in the prime minister but is holding off for now as the party believes May is likely to win.
"The government has lost control of events and is in complete disarray," he warned on Monday.
Eurosceptic MPs in May's Conservative party also repeated calls for her to be replaced, with one warning it was time to "govern or quit".
