Britain is to lend Ukraine an additional £2.26bn and allow Kyiv to spend the money on weapons to fight off the Russian invasion as part of a wider $50bn (£38.5bn) loan programme expected to be confirmed by G7 members later this week.
The loans will be repaid using interest generated by the $300bn of frozen Russian assets held in the west, with the extra funds promised as the US heads towards a presidential election where support for Ukraine is a divisive issue.
