The fraud trial of Allen Stanford has been delayed in the US after a judge heard psychiatric evidence he is suffering from depression.
Although the trial was due to start on 24 January, US District Judge David Hittner has now postponed it, with no new date set yet, after he was told of Stanford's depression and addiction to anti-anxiety medication.
Victor Scarano, a psychiatrist testifying for the defence, said: "In my opinion he's unable to work effectively with his attorney to develop a defence against the charges."
Stanford has already pleaded not guilty to fraud, conspiracy and obstruction after allegations he ran a pyramid scheme based in Antigua which defrauded investors of $7bn (£4.5bn).
Prosecutors have argued he "promised returns that were too good to be true", persuading investors to buy certificates of deposit from Stanford International Bank.
Stanford surrendered to US authorities in June 2009 and has been held in a Texas jail since then.
