UK Speaker said he would not allow another vote if it remained 'substantially same' after it was defeated by 230-vote margin in Jan.
London: Embattled British Prime Minister Theresa May's crisis over the Brexit in the UK Parliament has worsened as House of Commons Speaker John Bercow disallowed any attempt to hold a third vote on her withdrawal agreement with the EU which has already been voted down by MPs twice.
Bercow ruled that he would not allow another vote on the government motion if it remained "substantially the same" after it was defeated by a huge 230-vote margin in January and a smaller 149-vote margin last week.
He said parliamentary conventions dating back to 1604 meant MPs could not be asked to vote on precisely the same subject twice, indicating that he had allowed the second vote as the government had claimed some changes to the controversial Irish backstop clause offered an improved deal for Britain's exit from the European Union (EU).
"It is a necessary rule to ensure the sensible use of the House's time and the proper respect for the decisions which it takes," he said.
"If the government was to bring forward a new proposition that is neither the same, nor substantially the same as disposed of by March 10, this would be entirely in order," he said, adding that the new motion could not be "the same proposition or substantially the same proposition".
The Speaker, who is in charge of selecting the motions and amendments that the Commons votes on, said the second meaningful vote motion on May's Brexit deal held last week did not fall foul of parliamentary convention because it could be "credibly argued it was a different proposition" to that rejected on January 15 because of changes the government considered to be legally binding. Bercow's latest ruling comes as a fresh blow to May, who had been hoping she may get third-time lucky if she could win over enough rebellious MPs by warning that Brexit itself was in jeopardy unless she can go back to the EU with a substantial deal in place.
She is set to head to Brussels later this week for a European Council summit where EU leaders will contemplate agreeing to an extension of the March 29 Brexit Day deadline.
May had been hoping to seek a short extension until June 30 if her withdrawal agreement had cleared the Commons in a third vote before that meeting. However, the likelihood of the EU agreeing to a short extension under the current scenario will prove tricky, and any longer extension would mean the UK contesting the European Parliament elections scheduled towards the end of May.
The many opponents of the British PM's Brexit deal welcomed the Speaker's ruling, while others feared it had triggered a constitutional crisis just days ahead of the March 29 deadline. While MPs have also voted against leaving the EU without a deal in place within that time-frame, March 29 remains the default exit date unless the economic bloc ratifies an extension and it is then voted into law in the UK.
