UK and Russia trade accusations over Ukraine and Navalny poisoning

The UK and Russia are in a tense diplomatic standoff involving several issues. The UK expelled a Russian diplomat after accusing Russia of spying, and a UK official said action should be taken against Russia over the poisoning of opposition figure Alexei Navalny.

Meanwhile, Russia claims UK troops are active in Ukraine and that a UK official disrupted peace talks. A Russian diplomat in London also stated that Western plans to send troops to Ukraine are now 'dead'.
