Britain's Prince Charles' closest aide has quit.
Sir Michael Peat, 61, has been the prince's most trusted advisor for nine years and although he has decided to return to the private sector, he will continue to provide advice and work on financial projects for the prince on a part time basis once a successor to his post has been found.
On making the announcement he said working for Charles and Camilla has been "a life-changing experience" as well as "interesting, stimulating, challenging and fulfilling".
He added: "I have learned a huge amount and will be forever in His Royal Highness' debt; but after nine years the time is right for a change, for their royal highnesses' household and for me."
A spokeswoman for Clarence House said: "The Prince of Wales and the Duchess of Cornwall fully understand Sir Michael's wish to return to the private sector, are hugely grateful to him for all he has done, and wish him every success in the future."
A former chartered accountant, Sir Michael - who was also the Queen's treasurer, Keeper of the Privy Purse, from 1996 until 2002 - led the 2003 inquiry into claims of misconduct in the royal household and helped to organise Charles' marriage to Camilla, Duchess of Cornwall in 2005.
