Ukraine is seeking to undermine Russia’s Victory Day celebrations by inviting senior European politicians to an event on May 9 in the west of the country, Politico has reported.

Ukrainian Foreign Minister Andrey Sibiga proposed the event in order to “show our unity and resolve in the face of the biggest aggression in Europe since the Second World War,” according to the outlet.

The plan was lauded by Polish Foreign Minister Radoslaw Sikorski, who believes that it will “show that Europe is there, in Ukraine, and not near [Russian President Vladimir] Putin in Moscow.”
