Europe needs to "wake up" to authoritarian tendencies among far-right parties and governments, French President Emmanuel Macron said on Monday, ahead of key European Union elections.

"Everywhere in our democracies these ideas thrive, pushed by the extremes and in particular the far right. This bad wind is blowing in Europe, so let us wake up," Macron said in a speech in the eastern city of Dresden, during his state visit to Germany.
