Austrian Chancellor Sebastian Kurz has asked for a snap election after his Vice-Chancellor, Heinz-Christian Strache, resigned over a corruption scandal.

Mr Kurz's centre-right People's Party is in government with Mr Strache's far-right Freedom Party.

The Freedom Party leader stepped down after secret video footage emerged.

The video appears to show him discussing government contracts with an alleged Russian investor.

Mr Strache blamed his actions on alcohol and acting like a "teenager", saying his behaviour had been "stupid" and "irresponsible", and that he was leaving to avoid further damage to the government.

"I have suggested to the president of the republic that new elections be carried out, at the earliest possible date," Mr Kurz said.

"After yesterday's video, I must say quite honestly: Enough is enough," he said.
