Zelensky in UK for surprise meeting with Sunak
Ukraine's President Volodymyr Zelensky is visiting the UK to meet Prime Minister Rishi Sunak, BBC reports.

In a tweet, he said he would meet his "friend" Mr Sunak to hold "substantive negotiations".
The UK announced on Thursday that it would supply Ukraine with the long-range missiles it had requested to fight the Russian invasion.
Mr Zelensky has been meeting Western leaders in recent days seeking to bolster support for Ukraine.
At the meeting, Mr Sunak said the pair would be "discussing what more we can do to support" Mr Zelensky and Ukraine. The Ukrainian leader is the first foreign dignitary to meet Mr Sunak at Chequers, the prime minister's official country residence. Mr Zelensky's trip to the UK will be the fourth stop on a European tour that included meetings in Paris, Berlin and Rome.
Ukraine secured a new defence aid package worth $2.93bn (£2.4bn) from Germany after talks in Berlin with Chancellor Olaf Scholz on Sunday, taking its total military funding to nearly $7bn (£6.44bn).
Mr Zelensky described the new pledge of German Leopard tanks and anti-aircraft systems as "the largest since the beginning of the full-scale aggression" by Russia in February 2022.
France has promised dozens more light tanks and armoured vehicles after President Emmanuel Macron met his Ukrainian counterpart in Paris.
The US has given $46.65bn (£37.35bn) in military aid to Ukraine, far more money than any other country is donating. The UK comes second with $7.16bn (£5.17bn) in military aid.
In February, Mr Zelensky visited London for the first time since the start of the war, during which he attended an audience with the King and addressed Parliament.
His visit to the UK comes ahead of a G7 gathering in Hiroshima, Japan, later this week which will also be attended by Mr Sunak.
