Former Prime Minister Boris Johnson says that the UK and its allies should deploy non-combat troops to Ukraine right now, to "flip a switch" in Russian President Vladimir Putin's head.
Speaking exclusively to Sunday with Laura Kuenssberg alongside the former head of the military, Adm Sir Tony Radakin, Johnson said troops should be sent to peaceful regions in non-fighting roles.
He said: "If we can have a plan for boots on the ground after the war, after Putin has condescended to have a ceasefire, then why not do it now?"
The UK government is currently working with its allies to plan a "coalition of the willing" to provide forces to preserve peace and stability in Ukraine, but only if there is a deal to end the war.
Speaking just days before the fourth anniversary of the war, Johnson, who was prime minister at the time of the invasion, also said the conflict could have been prevented if Western allies had paid more attention to Putin's increasing aggression and his annexation of Crimea in 2014.
