John Willis to leave the BBC

The BBC's Director of Factual and Learning John Willis is to step down from the organisation after three years.
BBC Director-General Mark Thompson said: "John is one of the most respected creative leaders in British broadcasting.
"At the BBC, he has presided over groundbreaking programmes like Planet Earth, The Secret Policeman and the launch of BBC jam.
"As a member of the Executive Direction Group he has been a key figure in helping shape the direction of the BBC's Creative Future content strategy.
"I am grateful to John for the work he has done in strengthening and simplifying F&L. I fully support the changes he and his colleagues have made there.
"As we shape BBC production to deliver Creative Future we intend to build on the strong base John has laid.
"We talked about various roles for John as we begin to implement Creative Future but he has decided to take the opportunity to retire from the BBC and pursue other avenues. We all wish him the very best."
John Willis said: "My three years here have been book-ended by two of the most important programmes the BBC has made in the last 20 years, 'The Secret Policeman' and 'Planet Earth', as well as many brilliant programmes in between including 'Live 8', 'Dunkirk' and 'Auschwitz'.
"We have also established F&L as world class producers of digital content across new platforms and launched a new era in schools broadcasting with BBC jam.
"This marvellous content has been produced despite almost continuous change.
"Now that the organisation is also planning a BBC-wide restructure, I believe this is the right time for me to retire from the BBC, although certainly not from broadcasting."
