LONDON: British Foreign Secretary David Lammy expressed his concern on Thursday about a meeting between former UK prime minister Boris Johnson and Republican presidential candidate Donald Trump.

Speaking on the LBC radio morning show, Lammy admitted to presenter Tom Swarbrick that he had not been aware the meeting was taking place.

Johnson posted a picture on social media of him meeting Trump at the Republican National Convention in Milwaukee, after which he said the former president was “on top form” and that they had discussed the Russia-Ukraine conflict.

The foreign secretary was asked if Johnson had followed protocol by informing the UK Foreign Office of his meeting with Trump, to which Lammy replied: “I’m not sure that Boris Johnson consults either Keir Starmer or us on his plans. And I certainly didn’t know.”

Lammy refused to be drawn when pressed by Swarbrick on whether the meeting went against “UK national interests” or not.

“The record will show that I had a friendship with Barack Obama, prior to him becoming president of the United States of America, and about a year or so into office, he was dealing with David Cameron (as prime minister),” he said.

“I would never have done anything to prejudice the UK national interests at that time. So the point you’re making is a serious one. I would hope that all former prime ministers would act in the UK national interests and not cut across us, particularly two weeks into office.

“You know, I’m not interested, actually, in the past. I’m interested in the future.”
