Two accountants at the centre of a £100 million fraud have been found guilty following a trial in Birmingham which saw celebrated composer Lord Andrew Lloyd Webber and broadcaster Sir David Frost give evidence.
Shinder Gangar and Alan White were also found guilty of conspiracy to corrupt a US official after the trial which began at Birmingham Crown Court last summer following a five-year investigation.
The two accountants were found to have defrauded clients out of cash through high-yield investments.
Gangar (46) and White (49), who ran Leicester accounting firm Dobb, White & Co, both denied the two charges of conspiracy to defraud between 1996 and 2005 and one charge of conspiracy to commit corruption.
They insisted there was a real investment programme, which promised attractive returns.
The programme was being run covertly by the Federal Reserve Bank in the USA, who were denying it, the defendants alleged.
Last November, both Lord Webber and Sir David were each in the witness box of Court One for about quarter of an hour giving evidence during the trial.
The pair had been introduced to Gangar who was attempting to recruit them into the investment scheme.
Lord Webber told the court he did not understand the highly-complex scheme and passed on the details to his financial aide.
The scheme, which involved off-shore accounts offering spectacular returns, appeared to be too good to be true to Jonathan Webster, the composer's business manager, and no money was invested.
Sir David Frost told the jury that he and film producer Jonathan Stables were looking six years ago to make a gangster film, called Jack Spot, set in the 1950s.
He was introduced to Gangar as a potential investor in the project and they met in the 68-year-old presenter's offices. Sir David said the film was never made, and that he had never received any money from his business dealings with Gangar or allowed him to use his name to be used to promote the investment scheme.
A spokesman from the Serious Fraud Office said: "In order to give the investment credibility, clients were told by the defendants that famous names such as Lord Andrew Lloyd-Webber and Sir David Frost were investors in the scheme.
"However, they were not and had no knowledge that their names were being used."
