Channel 4 boss Andy Duncan has resigned, saying he will leave before the end of the year.

The Chief Executive has had the job for five years and was in charge of the broadcaster during the Celebrity Big Brother race row in 2007 featuring Shilpa Shetty and Jade Goody.

He told the BBC that now was ‘an appropriate moment to hand on the baton to someone else and move on to a fresh challenge’.

Duncan told The Times that the end of Big Brother means there will be big changes at the broadcaster in the near future.

He said: “Channel 4 is facing a further period of change, with a fresh regulatory cycle looming and with the cancellation of Big Brother signalling the most significant creative renewal in our history.”

According to reports, it is thought that the Channel 4 boss will receive over half a million pounds in severance pay.
