Gavin Grey: UK correspondent on Prime Minister Sir Keir Starmer expressing 'commitment' to defence spending but not revealing a timeline - Heather du Plessis-Allan Drive

Prime Minister Sir Keir Starmer has said the UK has a 'cast iron commitment' to spending 2.5 percent of national income on defence - but won't attach a timeline to that promise.

Starmer has travelled to Washington for NATO's annual summit days after he won the general election.

UK correspondent Gavin Grey says there's concern a proposed review could delay these plans.
