BORIS Johnson’s leadership has damaged the UK’s relationship with Europe and the US and left the UK “totally isolated,” the SNP’s Westminster leader has claimed.

Ian Blackford added that the “only way to secure Scotland's future and promote our interests is by becoming an independent country, playing our part on key global challenges."

He was speaking as the Prime Minister attempted to defend previous disagreements with the new President, insisting that there was “far more that unites” the UK and the US than divides.

Joe Biden has previously called the Prime Minister a “clone” of Donald Trump.

On Sunday morning, speaking to broadcasters, Johnson said: “I think there is far more that unites the government of this country and governments in Washington at any time and any stage than divides us.

“We have common values, we have common interests, we have common global perspective.

“There is a huge amount of work we need to do together to protect those values – a belief in democracy, in free speech around the world, in human rights, in free trade, in the rules-based international order – all these things are currently under threat.

“You have the United States and Britain standing together as they have done in many times in the past to protect those values, so there is far more, I think, that unites us than divides us.”

Earlier in the day, in an excruciating interview, his Foreign Secretary initially refused to answer when asked if all votes should be counted in a democratic election.

After being pushed on the question numerous times on Sky’s Ridge on Sunday, Dominic Raab said: “Look in principle, yes of course – although I’m not going to get drawn into….”

Pushed on why he did not say this originally, the Foreign Secretary added: “Because what you’re really trying to do is to drag me into the legal claims about whether or not all the votes have properly been counted when you look at the mail votes, the votes in person and the claims that have been made, for example, about the posting of military ballots – so I just don’t want to get sucked into that.”

Blackford said this unwillingness to say that every vote should be counted “spoke volumes”. 

He said: “The Tory leader's refusal to condemn Donald Trump's false claims of fraud in the US election, or Dominic Raab's repeated refusal to say that every vote should be counted, speaks volumes. Boris Johnson's decision over the years to align himself so closely with Trump's narrow and toxic policies has solidified his reputation as 'Britain Trump.'

“Here in the UK, Boris Johnson's government – which Scotland did not vote for – has shown utter disdain and disregard towards the devolved governments. From Brexit, its power grab Internal Market Bill, and refusal to devolve crucial powers, the Westminster Tory government has trashed any notion of a union of equals.

“The Tory Prime Minister’s hostile Brexit approach and attempts to run down the clock has damaged cooperation and goodwill with our EU partners, harmed business confidence, and hit the economy

“Boris Johnson's attempts to copy tactics straight out of the Trump playbook at home and abroad have left him out in the cold - just like his 'friend' across the Atlantic. 

“It's clear beyond any doubt that Westminster is simply not working for Scotland. Our vision for an outward-looking, progressive, and fair society has been held back by years of regressive Westminster policies. The only way to secure Scotland's future and promote our interests is by becoming an independent country, playing our part on key global challenges."
