Boris Johnson has pledged to send 120 armoured vehicles to Ukraine, after meeting President Volodymyr Zelensky for talks in Kyiv on Saturday.

The Prime Minister said he made his unannounced visit to the Ukrainian capital as “a show of our unwavering support for the people of Ukraine”.

As well as the armoured vehicles, in a significant stepping-up of UK military support, Mr Johnson said Britain would also be sending new anti-ship missile systems.

It comes the day after he announced a further £100 million worth of UK military assistance, including anti-tank and anti-aircraft weaponry and so-called “suicide drones”, which loiter over the battlefield before attacking their target.

Following his meeting with the Ukrainian leader, Mr Johnson said in a statement: “Ukraine has defied the odds and pushed back Russian forces from the gates of Kyiv, achieving the greatest feat of arms of the 21st century.
