The prime minister is considering making a significant increase in defence spending, the BBC has learned.
Downing Street is mulling the idea of meeting an existing spending target earlier than planned at a potential cost of billions of pounds.
Sir Keir Starmer signalled his attitude over the weekend at the Munich Security Conference, telling world leaders: "To meet the wider threat, it's clear that we are going to have to spend more, faster."
The prime minister promised last year to spend 2.5% of national wealth – measured as gross domestic product (GDP) - on core defence by April 2027.
But he also set out an "ambition" to increase that spending to 3% of GDP in the next parliament.
