Forming an international coalition to provide humanitarian assistance to Ukraine, supporting Ukraine's self-defense, maximizing economic pressure on Russia, preventing a "creeping normalization" of Russia's actions in Ukraine, diplomatic ways of de-escalation with the full participation of Kyiv and the rapid strengthening of security in the Euro-Atlantic region, such a plan of the six points for defeating Putin in his aggression against Ukraine was announced by British Prime Minister Boris Johnson.

"Putin must fail. We must come together under a six point plan of action to ensure Putin fails in his ambitions," the head of the British government said on Twitter on Sunday.

"The world is watching. It is not future historians but the people of Ukraine who will be our judge," Johnson said.
