The $50bn support package agreed by G7 leaders today is "game-changing", Rishi Sunak has said.
The UK prime minister said it would support Ukraine on the battlefield and in its economic reconstruction - but would also send a "signal" to Vladimir Putin.
"The signal that will send, the deterrence, is as important as the actual practical support and that has been what we've been focused on," he said.
Mr Sunak said the money would be provided by the G7 as a loan and then secured against profits of seized Russian assets.
