Defence Secretary John Healey will travel to America today ahead of a meeting with his US counterpart Pete Hegseth on Thursday.
The trip, which was agreed after the UK announced an increase in defence spending to 2.5% of GDP last week, comes days after the US paused military aid to war-torn Ukraine.
Ahead of the visit, Healey praised the “special relationship” between the UK and the US and said it is “crucial that the UK and Europe step up further to take more responsibility for our security, and we are doing so”.
“In the face of increasing global threats, we are cementing our ties as Nato allies, bolstering our national security and economic security, too,” he added.
“The Prime Minister was clear following his meetings over the past week that we will continue our dialogue with friends and allies to secure a path to a lasting peace in Ukraine.
“We will advance that work in Washington over the coming days.”
