Burnham says he is prepared to call out Trump ‘if right for Britain’

Burnham said: “My strength is remaining close to people, close to the public, that will not change as prime minister.”

Asked if he would call out Trump if it was the right thing, he said, “of course”, going on to say: “You have to defend your own national interest before anything else. That’s what you’re required to do if you’re to do this job properly.”

Burnham also said he had had “concern” about the president starting the conflict with Iran, and he “wouldn’t hold back from saying what I think is right”.

The prime minister would not commit to a date when the government would spend 3% of GDP on defence. His Chancellor John Healey resigned from the previous government saying that unless a commitment was made to spend that amount by 2030, the country would not be safe.

But Burnham said: “I appointed my new chancellor very aware of what he had said about the critical importance of defence spending and the position that he had taken about that.

“The first challenge facing us both is to ensure that the defence investment plan is fully funded and that’s the thing that’s right in front of us and we need to work that through as we go towards the budget later this year.”
