NICOLA Sturgeon has accused the UK Government of “pathetic cowardice” should rumours about a delay to tomorrow's meaningful vote turn out to be true.

MPs are due to vote on Theresa May's Brexit deal at Westminster tomorrow, but with the Prime Minister facing a humiliating defeat – and thus the possibility of a people's vote or a General Election, among several other scenarios – rumours are growing that that vote will now be delayed.

With Labour, the SNP, the DUP, the LibDems and least 108 of her own MPs against the deal, Theresa May is facing one of the biggest parliamentary defeats since Jim Callaghan’s government lost a 1976 vote 259 to nothing.

In response to National columnist Kirsty Strickland's tweet that a delay to tomorrow's vote would be an act of "cowardice", Sturgeon replied: "100% this.

"If rumours of a delay are correct, it will be pathetic cowardice by a PM and government that have run out of road and now need to get out of the way."

It was reported in yesterday's Sunday Times that May, in a last-ditch attempt to save her government from collapse, wants to delay the vote and travel to Brussels to demand concessions on the Irish backstop.

In the last hour, the BBC's Laura Kuenssberg tweeted that two Cabinet sources had informed her that they intend to pull the vote though it is yet to be confirmed.
