New Delhi, Jan 31 (KNN) A united chorus of "No" to Britain's belated bid to negotiate changes to the Brexit divorce deal was offered by the leaders across the European Union so that Prime Minister Theresa May can win the backing of her Parliament.

In London, May acknowledged that her government hasn't decided exactly how it will try to change the deal to address British lawmakers' concerns about the Irish border.

Britain and the EU struck a divorce deal in November after a year and a half of tense negotiations.

But the agreement has run aground in Britain's Parliament, which overwhelmingly rejected it on Jan. 15.

"We are, quite simply, running out of road," said Irish Foreign Minister Simon Coveney.

"We've been down that track before and I don't believe that such alternative arrangements exist," Irish Prime Minister Leo Varadkar said.

Buoyed by winning a vote in Parliament, May has vowed to secure "legally binding changes" to the withdrawal agreement.

British lawmakers voted Tuesday to send May back to Brussels seeking to replace an Irish border provision in the deal with "alternative arrangements," ignoring EU warnings that the agreement cannot be altered.
