David Coulthard has suffered a tragic blow after his sister Lynsay Jackson was found dead in her home in Scotland on Saturday morning.

The 35-year-old, who has an eight-month-old daughter, used to run her brother’s fan club as well as the David Coulthard Museum in Twynholm.

The former McLaren and Red Bull driver was reportedly told the bad news just before appearing live for an interview on a TV cooking show.

"He wanted to put on a brave face and just get the show done," said BBC commentator Coulthard's agent.

The Sun newspaper said police believe Lynsay Jackson died after a sudden unexpected illness.

"Our inquiries into her death are ongoing at this time, but there are not believed to be any suspicious circumstances and a report is being prepared for the procurator fiscal," a police spokesperson investigating the case is quoted saying by the BBC.
