BORIS Johnson has accused the SNP of having a "crackpot plan" for Scottish independence during a bizarre anti-independence rant in the House of Commons

During PMQs, SNP Westminster Ian Blackford had accused the Prime Minister of being "willing to throw Scotland under his big red bus to deliver his Brexit no matter what the cost".

In response, Johnson gave a long and rambling rant over his opposition to Scottish independence.

He said: "As the Right Honourable Gentleman knows very well the greatest damage that can be done to the Scottish economy would be their reckless plan to break up the Union with the UK – 60% of Scotland’s exports is with the rest of the UK, they would be throwing away not just the biggest block grant in history that Scotland has received this year but of course all the benefits of membership of the most successful political partnership in history – from shipbuilding in Govan to the Glasgow climate change summit next year. Which will be a glory of our whole United Kingdom and is coming to Scotland precisely because Scotland is part of the United Kingdom."

Last month, Johnson had suggested he would ban First Minister Nicola Sturgeon from that event.

He continued: "And they would throw all that away Mr Speaker with their crackpot plan for borders at Berwick and creating a new Scottish currency or joining the euro, or worse still, going into the European union, handing back control of Scotland’s fisheries – Scotland’s spectacular marine wealth just at the moment that they’ve been won back by this country, handing back control of those fisheries to brussels. That’s their policy Mr Speaker I look forward to contesting it at the barricades."

Blackford said he thought "it was Prime Minister’s Questions not a rant from the Prime Minister".

The MP for Ross, Skye and Lochaber went on: "You know, we hear that the Prime Minister’s going to be coming up to Scotland on the election campaign. Can I tell the Prime Minister he’s welcome – because each time he comes to Scotland he drives SNP support up.

"Mr Speaker Scotland didn’t vote for Brexit and we wont have it forced upon us. Isn’t it clear that the SNP is the only party standing up for Scotland’s interests and respecting our democratic decision to Remain in the European Union. Mr Speaker this coming election will be one of the most important in Scotland’s history. Only a vote for the SNP can secure the escape route for Scotland away from this Brexit mess. From the chaos of Westminster, the austerity of the Tories, and to respect Scotland’s right to choose our own future as an independent country in Europe."

Johnson said that while he was "sorry" for seeming to rant, Blackford had done the same regarding independence. "He bangs on about it endlessly. Why does he go on about Scottish independence? Its because he wants to conceal what the SNP Government is actually doing in Scotland Mr Speaker.

"They are wrecking … they are diabolical for the Scottish economy, they have the highest taxes in the UK, they are not running either health or education well. That is why they’re so monomaniacal about independence and smashing the Union Mr Speaker. Actually when I look at the good things happening in Scotland and there are some wonderful things happening it is very often thanks to Scottish Conservatives who are delivering £200m for Scottish farmers – all thanks to the … of Scottish Conservatives.

"The biggest ever block grant from London to Scotland Mr Speaker. And of course it is Scottish Conservatives who can be relied upon unlike any other party in Scotland – unlike Labour, unlike the SNP – to keep the Union together. The most successful political partnership in history."
