Sir Elton John has launched a massive legal battle against his business manager of 30 years Bob Halley.
Sir Elton, 60, and the parent company of his business empire William A Bong Ltd, have issued a writ in the Royal Courts of Justice against Halley.
Halley, 61, has worked for the flamboyant singer for more than three decades and over that time has acted as personal assistant, chauffeur, director of operations, and business manager.
William A Bong is the main holding company for Sir Elton's other companies, which include Happenstance and formerly John Reid Enterprises Ltd, and in 2004, the company's accounts showed a fall in income of more than £5 million.
The lawsuit was filed in court by solicitors acting for Sir Elton on Tuesday, and since then his legal firm made a successful bid to have the court action heard in secret.
No more information about the case is so far available and as yet no date has been set for a hearing.
In the early ninieties, Sir Elton had a spectacular falling out with another of his managers, fiery Scot John Reid, and later accepted a £2.5 million settlement from him.
Sir Elton is no stranger to the courts. In 2000, he sued his former accountants PricewaterhouseCoopers and former agent Andrew Haydon for £20 million after accusing them of negligence.
He has also issued a series of writs for libel against newspapers.
Born plain Reg Dwight, Sir Elton later changed his name to Elton Hercules John.
