SIR Keir Starmer will have to wait at least another week to visit Donald Trump — as he heads to Brussels first.

The PM will meet the leaders of the EU 27 to discuss signing Britain up to a defence treaty with the bloc as well as meeting other European leaders this weekend.

The new President and the PM agreed to “meet soon” when they spoke on Sunday.

But No10 sources said last night no date had yet been set for a dash to DC.

Last night it was reported Lord Mandelson had “told friends” his controversial appointment to be the next UK Ambassador to the US had been given the greenlight by the Trump White House.

It came amid claims his relationship with China had been reported to the FBI by concerned American senators.

Meanwhile, Trump’s secretary of state warned Foreign Secretary David Lammy to beware China’s “malign influence”.

It came as the White House scrutinises Britain’s deal to cede sovereignty of the Chagos Islands.

Marco Rubio stressed the need for a “free and open Indo-Pacific that is secure and stable” in his first call with Mr Lammy.
