Businessman and television personality Duncan Bannatyne provided false evidence during a divorce money fight with his former wife, a judge has said.
Judge David Hodge said Mr Bannatyne's aim was to mislead a court for financial gain.
The judge said Mr Bannatyne later corrected "the situation".
Detail emerged in a ruling by the judge after Mr Bannatyne became involved in a legal fight with a newspaper publisher over whether the public could be told what he did.
The judge ruled in favour of Associated Newspapers, which publishes the Daily Mail and the Mail on Sunday.
He said there was a public interest in exposing attempts to mislead a court even if the person making such attempts had repented.
Mr Bannatyne was ordered to foot lawyers' bills run up by Associated Newspapers.
Judge Hodge analysed the dispute at a High Court hearing in Manchester last month.
