Boris Johnson has told MPs that Britain is looking at “going up a gear” in its military assistance to Ukraine, potentially supplying armoured vehicles to help relieve the besieged city of Mariupol.
And the prime minister said that in the long term, the UK and its Western allies need to undertake a “total rethink” of the way that Ukraine and other former Soviet states are protected from Russian aggression, ensuring that they are so fortified with Nato weapons that Moscow would not dare invade.
