Appearing on the station's breakfast show less than 24 hours after news of Mandela's death was announced, the former Pop World presenter joked about racial segregation between different aspects of BBC Radio and referenced the late South African leader.
During the show on Friday, he said: "What is going on? We're next to (urban music station) 1Xtra, it's so white in here. Mandela would not approve of the situation at the BBC."
Amstell took his Twitter account later the same day to apologise for the joke, writing: "It may have been unclear this morning, as things often are but what came out of this mouth today was silly. Apologies to everyone involved."
