Kyle Sandilands has resigned from his role on Australian Idol, citing pressure from an activist group that has targeted the show's advertisers. Sandilands announced his decision on Friday, stating that he did not want the controversy to harm the program's brand.

"I spoke with Channel Seven this morning, and those activists have attacked the potential clients for Australian Idol or the clients from last year, and this has caused a problem in Channel Seven’s sales team," Sandilands told The Sydney Morning Herald. "So I’ve told Channel Seven this morning, just prior to speaking to you, that I’m standing down from Idol for the good of the brand to continue."

The activist group, identified as the Mad F

king Witches, has campaigned against Sandilands for years. The group has previously accused the radio personality's on-air content of misogyny and offensive remarks. Their efforts have previously targeted corporate sponsors during his tenure at KIIS FM.

Sandilands' departure aims to mitigate further damage to Australian Idol, a decision made in communication with Channel Seven executives.
