Britain has completed military training in Ukraine and the only remaining British military personnel in the country are there to protect the ambassador, British Defence Secretary James Heappe said.

The UK has supplied Ukraine with defensive weapons and training personnel.

"Within Ukraine itself, there is a small force that remains for the purposes of protecting the ambassador and her team," Heappey told BBC Television. "Beyond that, all of our training activity alongside the Ukrainians has been ceased and we've been very clear throughout that there will be no UK involvement in any conflict in Ukraine."
