The SNP’s Westminster leader has said another EU referendum must be on the table for cross-party Brexit talks to take place with the Prime Minister.
Ian Blackford called on Theresa May to make concessions on her withdrawal deal, after she survived a confidence vote in Parliament on Wednesday.
He also urged Jeremy Corbyn to back a so-called People’s Vote.
Mr Blackford said: “The SNP is committed to working constructively with the Prime Minister, however the option of ruling out a No Deal, extending Article 50 and holding a People’s Vote must now be on the table.
“I have written to Jeremy Corbyn along with other opposition leaders calling on him to support a People’s Vote on the final Brexit deal.
“Last night’s historic vote, which saw the UK Government humiliated, was a clear indication of the strength of opposition to the Prime Minister’s deal from across the House. We must see concessions from the Prime Minister, as well as Jeremy Corbyn, to break the Brexit impasse.”
Mrs May invited party leaders to discuss how to progress with the Brexit deal, after winning the confidence vote by 325 to 306.
But the SNP also wants guarantees that ruling out a No Deal and extending Article 50 will be possible options.
Ahead of any talks, the SNP wrote a cross-party letter with the Liberal Democrats, Plaid Cymru and the Greens to the Labour leader.
It argues that “now that the Government and the Official Opposition’s options have been tested before the House, we believe the only way now which presents a real chance of breaking the Brexit deadlock is to put the decision to the people by backing a People’s Vote.”
