The Marussia F1 team says it is "shocked and angered" by some media reports claiming Jules Bianchi did not slow down under caution flags at the Japanese Grand Prix.

The French driver is in a critical but stable condition in hospital following a crash in the race at Suzuka 10 days ago, which left him with severe head injuries.

Yesterday, Bianchi's father, Philippe, said his son's situation is "desperate" but added he is sure Jules "will not give up" fighting for his life.

But the Marussia moved to quash reports that Bianchi did not slow down in the moments leading to the accident.

"Jules did slow down under the double-waved yellow flags. That is an irrefutable fact, as proven by the telemetry data, which the team has provided to the FIA. In the FIA press conference which took place in Sochi on Friday 10 October, Charlie Whiting, the FIA’s Race Director, confirmed that the team had provided such data, that he himself had examined this data and that Jules did slow," said the team in a statement.
