Darren Tallon, who defrauded Princess Yachts of more than £800,000, has been ordered by the judge overseeing the case to pay back around £500,000 or remain in prison.

Tallon, according to The Plymouth Herald, must sell properties he owns in Plymouth and land in Canada to repay the boatbuilder. The four other men involved in defrauding Princess have already been ordered to pay back over £300,000. The five billed Princess in a series of complex frauds for more than £1m for work that never took place.

Judge Paul Darlow, who presided over the trial two years ago, ordered Tallon pay back £552,237 under the UK Proceeds of Crime Act. If he does not repay the money within three months, he faces a five-year prison sentence. He is currently serving a sentence of four years and six months, which started in April 2016.

Among the other four, Glyn Thompson was jailed for six years, while Roger Truen was imprisoned for more than three years. John Tinley and Michael Honey also admitted taking part in the plot to defraud Princess Yachts. But they received suspended prison sentences after they gave evidence against the others.

Thompson was said to have made £636,945 over about three years of defrauding Princess. He only has assets worth £8,000, according to the paper. Truen received £617,051 but his assets only amounted to £147,998.
