THE SNP’s Westminster leader has poked fun at Labour after they were accused of interfering in the US election by Donald Trump.

It comes after Keir Starmer insisted his relationship with the presidential candidate is not in jeopardy following the announcement that an official complaint had been filed with US federal election officials.

The complaint follows reports of senior Labour officials meeting with Kamala Harris’s (below) campaign, and Labour Party staffers volunteering on the ground for her campaign.

Speaking at PMQs on Wednesday afternoon, Flynn asked Deputy Prime Minister Angela Rayner: “In today’s spirit of cross-party working, will the Deputy Prime Minister join me in applauding the brave Labour staff members who’ve travelled across the Atlantic to campaign against Donald Trump?”

Starmer has insisted that any members of his party were in the US on an entirely voluntary basis, similar to in previous elections.

Scottish Liberal Democrat leader Alex Cole-Hamilton has also responded to criticism for heading to the US to campaign for Harris.

Responding to Flynn’s question, Rayner echoed the PM’s lines that any party members were in the United States on a voluntary basis.

She said: “I say to the honourable gentleman is that people in their own time often go and campaign and that’s what we’ve seen.

“It happens in all political parties, people go and campaign and they do what they want to do in their own time with their own money.”

Starmer met with Trump (above), the Republican presidential nominee, during a trip to New York last month.

The Prime Minister visited Trump Tower for talks ahead of the US election, and said he wanted to meet the former president face-to-face because “I’m a great believer in personal relationships on the world stage”.
