Gordon Ramsay, (below) the celebrity chef, is being investigated by the taxman for "serious fraud" involving his restaurant business.
A friend of Ramsay said yesterday that he is working with the authorities and said the problems took place under "previous management".
Ramsay sacked his father-in-law Christopher Hutcheson as chief executive of his company after discovering he had raised a secret family.
After a series of bitter legal battles Mr Hutcheson reached a reported £2m settlement with Ramsay earlier this year for his 30pc stake in Gordon Ramsay Holdings.
However, yesterday it emerged that Mr Hutcheson has made an application to the Companies Court to have the business wound down over an alleged £600,000 debt. A registrar will rule on the case in January.
Ryan Carthew, Mr Hutcheson's solicitor, said: "One of the reasons Mr Hutcheson has taken this drastic step is that he understands that there's a serious investigation into the tax affairs of Gordon Ramsay Holdings."
Mr Ramsay's feud with his father-in-law began after he discovered that Mr Hutcheson had two children with Frances Collins, his mistress. He had four children with Greta, his unsuspecting wife, dividing his time and wealth between his two families. Tana, Mr Ramsey's wife, sided with her husband after learning her father had raised a second, secret family for 30 years. (© Daily Telegraph London)
