Ian Blackford has said that MPs must work together to prevent Boris Johnson from blocking MPs from preventing a no-deal Brexit. 

The SNP Westminster leader said that the Prime Minister proroguing parliament 'tramples over democracy', although Downing Street has since denied that the Prime Minister is considering suspending the Commons. 

When reported, Downing Street responded dubbing them 'entirely false'

Speaking on Good Morning Scotland, Ian Blackford said MPs had a duty to Parliament and their constituents to make sure that they had a say on the future of Brexit. He also dubbed the reported effort to shut down parliament to secure a no-deal Brexit as a "constitutional crisis"

"We had the authoritative report at the weekend, and we've had other leaks that have come out of Downing Street that absolutely confirm that this (proroguing parliament) is well and truly on the agenda and it's Boris Johnson and his government running scared because they know there is a majority of parliament that will do everything they can to stop no deal. 

"We need to reflect on the fact that Boris Johnson has become Prime Minister on the votes on Conservative members of Parliament. He doesn't have a mandate from the voters, and at no point has any party, and indeed in the referendum in 2016, was the proposition put forward that we would be leaving the European Union on a no-deal basis. 

"He needs to be stopped and I am appealing to Parliamentarians this week to recognise the responsibility collectively that we've all got. We have to move fast, we are up against a Government that are prepared to crash the bus and that has to be stopped.

"When we get back on September 3rd, we need to seize the moment of taking control of the order paper, which we do through something called Standing Order 24, that will then allow MPs to determine the business that's brought forward to the house, not the Government, and we can then bring forward the bill that can remove that cliff edge of 31st October. This is now something we can't run away from."

Earlier this month, Labour leader Jeremy Corbyn put forward a proposal to act as a caretaker prime minister in the event of winning a no-confidence vote against the Government.

Mr Corbyn indicated he would then move to extend Article 50 to avoid crashing out of the EU with no deal in place, before calling a snap general election.

And Mr Blackford said the SNP would be ready to work with anyone in order to avert a no-deal scenario.

He said: “We will work with anybody and everybody to stop this and it’s not about who becomes prime minister in the short-term – in many respects we don’t even need to do that.

“What we need to do is stop no-deal and we need to stop the damage that Boris Johnson will do.

“We need to bury our differences and we need to recognise the challenge that we face from someone that’s prepared to take us out of the European Union on a no-deal basis.

“We all need to work together, that’s what the public would expect from us. It’s about protecting the interests of all our constituents from Brexit.”

On Monday, Liberal Democrat leader Jo Swinson wrote to Mr Corbyn claiming that his plan to put himself forward as a caretaker prime minister could jeopardise efforts to stop a no-deal Brexit because he does not have enough support in Parliament.

“It’s not about whether or not Jeremy Corbyn has support, it’s about the responsibilities we have as members of Parliament,” said Mr Blackford.

“What we need to do is bring forward legislation and I’m disappointed that Jo is playing games like this.

“All of us have to work together – it’s not about the individual, it’s about making sure that we put in place legislation to stop no-deal.”
