Ukraine's President Zelenskyy is in London meeting British Prime Minister Rishi Sunak on Wednesday, marking his first visit to the U.K. since the war began.
The visit comes at a difficult time for Ukraine as it prepares for an expected large-scale offensive by Russian forces, and as its military looks to retain control of Bakhmut in Donetsk, east Ukraine.
Russian and Ukrainian forces have been battling for control over the city for months but Russia recently claimed that it has almost encircled the city, and on Wednesday one military commander said Russian troops now occupy several streets in the city.
