UK Prime Minister Boris Johnson will lay out a six-point plan of action on the Russia-Ukraine war during meetings with Canadian, Dutch, and Central European leaders next week, CNN reported.

Johnson is set to tell his counterparts they must come together under his plan to ensure Russian President Vladimir Putin “fails in his ambition,” according to a Downing Street news release on Saturday.

The plan, according to the news release, calls on countries to mobilize “an international humanitarian coalition for Ukraine, support Ukraine in its efforts to provide its own self-defense and maximize the economic pressure on Putin’s Russia.”

According to the news release, the plan also calls on the UK’s partners to “prevent the creeping normalization of what Russia is doing in Ukraine, pursue diplomatic paths to de-escalation but only on the basis of full participation by the legitimate government of Ukraine and begin a rapid campaign to strengthen security and resilience across the Euro-Atlantic area.”

“Putin must fail and must be seen to fail in this act of aggression,” the release said. “It is not enough to express our support for the rules-based international order – we must defend it against a sustained attempt to rewrite the rules by military force.”
