Three-times Formula One world champion Niki Lauda has died at the age of 70, his family says.

The Austrian took the title for Ferrari in 1975 and 1977 and McLaren in 1984.

He was badly burned in a crash in the 1976 German Grand Prix, but recovered and returned to racing. He was also a pilot and set up two airlines.

In January, he spent some 10 days in hospital while suffering from influenza. Last August, he had a double lung transplant.

“With deep sadness, we announce that our beloved Niki has peacefully passed away with his family on Monday,” his family said in a statement.
