Mr Blackford gave strong hints earlier this week that Nicola Sturgeon could be poised to announce a fresh push towards independence when he declared the SNP leadership would “not allow Scotland to be dragged out of the EU against the wishes of its people”. And today in the Commons he told the Prime Minister “Scotland is watching” as he repeated his calls for a second Brexit referendum after Mrs May confirmed she had written to Brussels asking for an extension to the March 29 departure date. He said: “Six days ago the Chancellor of the Duchy of Lancaster said in the absence of a deal, seeking such a short and critically one-off extension would be downright reckless.
“Downright reckless Prime Minister – does she agree with her de facto deputy that her actions this morning are downright reckless?”
Mrs May replied: “People voted for Brexit, we have a responsibility to deliver.
“I recognise he and his colleagues in the SNP have always taken the position they want to revoke Article 50 and not have Brexit.
“At least that’s a firm position which is different from the leader of the Opposition who has continually moved his position on this issue.
“But I also believe that nearly three years on from the vote having taken place, to deliver on Brexit for the British people, it is time for this House to face that fact, to face the consequences of its decisions and to deliver on Brexit for the British people.”
Mr Blackford repeated his demands for a second EU referendum.
He said: “Her deal had the biggest defeat in parliamentary history, she brought it back, it had the fourth biggest defeat in parliamentary history.
“Her deal has failed, this House has voted against no-deal, once again the Prime Minister is acting in her own self-interest, not in the interests of the whole of the UK.
“The Prime Minister has failed, this place has failed and Scotland is watching. The only way forward now is to put the decision back to the people.”
He continued: “Will the Prime Minister give the people a say in such a referendum? The people of Scotland deserve a choice over their future.
“If Westminster fails, Scotland will act.”
Earlier this week Mr Blackford said the SNP’s primary responsibility was to defend the economic interests of Scotland and said if Brexit was going harm the nation then “of course, we have to take the action that’s in the best interests of the people of Scotland”.
He said: “We understand the responsibilities we have got and I would say to Westminster that if the First Minister does recommend that the Parliament exercises the mandate that it has from 2016 to have an independence referendum with a desire that an independent Scotland remains in the EU, then we must and we will have that vote.”
