Sir Keir Starmer met the US commerce secretary in Downing Street last night, as No10 desperately tries to get Donald Trump to lift tariffs on cars and steel as soon as possible.

The Prime Minister dropped in on a meeting between Howard Lutnick and Business Secretary Jonathan Reynolds in Downing Street on Tuesday, as the Government continues to push for its American trade deal to come into force.

Sir Keir and Trump hailed the broad terms of an agreement more than a month ago that would exempt the UK from some of the US president's punitive and widely criticised levies.

But the details are yet to be ironed out, despite warnings from industry that they could soon have to start looking at lay-offs.

Mr Lutnick was in London for talks with China on resolving the trade war between Washington and Beijing, and Mr Reynolds took the opportunity to meet him in person to push for the UK-US trade deal announced last month to be implemented as soon as possible.
