The government has announced a further £450m of military support to Kyiv, as the UK and Germany hosted a meeting of 50 nations in Brussels.
Defence officials met to "pile pressure" on Russian President Vladimir Putin and force him to end his invasion of Ukraine, UK Defence Secretary John Healey said.
"We must step up to deter Russian aggression by continuing to bolster Ukraine's defences," he added.
The package includes funding for hundreds of thousands of drones, anti-tanks mines and and repairs to military vehicles.
