International Desk: The then-prime minister said Mr Putin told him it “would only take a minute”. Mr Johnson said the comment was made after he warned the war would be an “utter catastrophe” during a “very long” call in February 2022.
Details of the exchange are revealed in a BBC documentary, examining Mr Putin’s interactions with world leaders.
Mr Johnson warned Mr Putin that invading Ukraine would lead to Western sanctions and more Nato troops on Russia’s borders.
He also tried to deter Russian military action by telling Mr Putin that Ukraine would not join Nato “for the foreseeable future”.
But Mr Johnson said: “He threatened me at one point, and he said, ‘Boris, I don’t want to hurt you but, with a missile, it would only take a minute’ or something like that. Jolly.
