Sunak's office said the funds, an increase of 200 million pounds on the previous two years, would help fund the procurement of thousands of military drones for Ukraine, including surveillance, long-range strike and sea drones.
"I am here today with one message: the UK will also not falter," Sunak said in a statement. "We will stand with Ukraine, in their darkest hours and in the better times to come."
