A British powerboat racer has been killed in a 120 mile-an-hour crash in west Africa.
William Nocker was competing in the Gabon Grand Prix when his boat flipped and "barrel rolled" on the water, according to witnesses.
The 47-year-old was rushed to hospital in Gabon's capital, Libreville, but doctors were unable to resuscitate him.
His co-driver, Norwegian Kurt Olsen, was also badly hurt and remains in a critical condition in intensive care.
Onlookers said Mr Nocker's boat appeared to have hit two waves in quick succession before the crash.
The Foreign Office is providing consular assistance to Mr Nocker's family.
Nicolo di San Germano, the president of race promoter H20 Racing, said: "We are all extremely saddened by this tragic racing accident.
"There are very few suitable words at a time such as this but we all send our heartfelt condolences to William's family."
Mr Nocker, who lived in Cheltenham, was returning to the sport following a five-year suspension after he was found guilty of tampering with a competitor's fuel supply.
A tribunal upheld charges of gross misconduct and unsportsmanlike behaviour against Mr Nocker and fellow racer Rob Lister.
Water had allegedly been poured into the tank of a rival boat during the Liverpool Powerboat Grand Prix in 2006.
