Australian shock jock Kyle Sandilands has been sacked from his ten-year, A$100m ($71m; £53m) breakfast radio contract, and his top-rating show with co-host Jackie "O" Henderson cancelled.

Sandilands, 54, was suspended from KISS FM's Kyle and Jackie O Show two weeks ago after an on-air spat with Henderson. ARN Media - the station's owner - accused him of serious misconduct, giving him 14 days to fix the situation.

The radio duo have dominated commercial breakfast radio for decades, with their brand of crude humour attracting high ratings, notably in Sydney.

On Wednesday, ARN said Sandilands' behaviour was a breach of contract, while the star countered that he would fight the decision in court.

It is not known how ARN's decision on Sandilands will impact Henderson's own ten-year $100m contract which was tied to presenting the station's flagship programme. Both were expected to remain on air until at least 2034.
