Prime Minister Boris Johnson has travelled to Kyiv, where it is understood he is having talks with Ukrainian President Volodymyr Zelensky.
Mr Johnson previously visited the Ukrainian capital in April.
He had been due to appear at a conference held by a group of his Tory MPs in Doncaster, but cancelled the visit to travel to Kyiv instead.
The visit comes as EU leaders back Ukraine’s bid to be given candidacy status to join the EU.
