SIR Keir Starmer has vowed to pump an extra £13 billion into defence, warning “tyrant” Vladimir Putin only responds to strength.
The PM laid out a plan to raise the military budget to 2.5 per cent of GDP within two years - and then to 3 per cent after the next election.
The cash boost will add an additional £13bn a year to armed forces coffers from 2027, according to the PM.
Writing exclusively for The Sun on Sunday, the PM urged President Trump to provide security guarantees for Ukraine.
He said: “Ukraine must have a voice in negotiations about its future. And it needs strong security guarantees so the peace will last. I believe America must be part of that guarantee. It’s in their interest.
“A peace deal which does not stop Putin from attacking again would be a disaster for everyone.
“The best way to make sure that doesn’t happen is to be firm and fair now.”
Earlier this week, Sir Keir Starmer has warned that a bad peace deal would be a "disaster".
Writing ahead of his crunch trip to Washington, Sir Keir said the US President is right to “grasp the nettle” and try to end the war.
But a good peace “can only be won with strength” and it requires the world to stand up to Vladimir “Putin’s tyranny”, the PM said.
He added that Ukraine must be at the heart of peace negotiations.
