The official said they hoped a deal would be struck during or shortly after a meeting between U.S. Trade Representative Katherine Tai and British trade minister Liz Truss on Wednesday.

A separate statement from the Department for International Trade said: "We have been working hard with the US to de-escalate and agree a settlement after making the first move in suspending tariffs.

"We look forward to continuing discussions on the long-standing Large Civil Aircraft dispute during Katherine Tai's visit to the UK on Wednesday, and achieving a fair and balanced settlement that works for the whole of the UK."
