The BBC's chairman, Lord Patten of Barnes, has stood down from the BBC due to health problems.
Lord Patten said in the BBC's statement that his heart condition means he can no longer continue working in such a high pressure role.
It has been a privilege to have served as Chairman of the BBC Trust. Like the NHS, the BBC is a huge national asset which is part of the everyday fabric of our lives. It is not perfect – what institution is? It always needs to challenge itself to improve. But it is a precious and wonderful thing, a hugely positive influence which benefits greatly from the creativity and dedication of its staff. I have had no reason to doubt that the leaders of all main political parties support the role it plays at the centre of our public realm. Most important of all, the British public enormously value the strength of its output, its independence and the contribution it makes every day to the quality of our lives.When in due course the future of the BBC is subject to further discussion at Charter Review time, I hope to say more on the issue. For the time being, however, I shall be making no further statement whatsoever about the BBC or my period as Chairman of the BBC Trust.
