Brexit will crash the economy, the SNP’s Westminster leader has warned.
Ian Blackford said any move by the UK Government to leave the EU without a deal is “madness”.
His comments come as Theresa May is to address EU leaders in Brussels in further talks on a Brexit deal amid falling expectations.
The SNP MP warned a no-deal Brexit would be a dereliction of duty from the Prime Minister.
Speaking on the BBC’s Good Morning Scotland radio programme, he said: “When you look at the fact that we’ve got a UK Government that’s burdened by debt of almost £1.8 trillion to put yourself in the situation that you are going to crash the economy, because that’s what you’re doing, this is absolutely unprecedented.
“UK Government analysis suggests that the Scottish economy could fall by as much as 9% over 15 years.
“This is madness. No government should be doing that.
“You have a responsibility to look after people and I’m charging the Prime Minister of not discharging that responsibility properly.”
He said we must “stop where we are” and recognise the consequences of leaving the EU without a deal and repeated calls for the remaining in the single market and customs union, for which he believes there is a majority in the House of Commons.
Mr Blackford added the issue of a referendum on the final Brexit deal, a so-called People’s Vote, should be looked at if either no agreement is reached between the UK and the EU or if it is a “bad deal”.
