Britain could provide Ukraine with tanks for the first time to help the country fight Russian forces.
Discussions have been taking place "for a few weeks" about delivering ten of British army's Challenger 2 main battle tank to Ukraine, Sky News reported on Monday, citing unnamed sources.
The British government has reportedly not yet taken a final decision on the matter.
The Challenger 2 is a battle tank designed to attack other tanks, and has been in service with the British army since 1994.
The UK Ministry of Defense did not comment specifically on possible supplies of tanks to Ukraine, but pointed to its supply of over 200 armored vehicles and other equipment including air defense missiles and anti-tank weapons to date.
Foreign Minister James Cleverly said last week that Britain would continue working with Western allies to provide military equipment to Ukraine.
"Tanks might well be part of that, and where they come from... which allies provide them, is something that, of course, we're working in coordination with each other," Cleverly said, following a meeting with his German counterpart.
