A former Dragons' Den star who acted as an adviser to Prime Minister David Cameron will go on trial in the new year on child sex charges.

Doug Richard is accused of three counts of sexual activity with a child and one of causing or inciting a child to engage in sexual activity.

The charges relate to a single complainant, a girl aged 13 at the time they are alleged to have taken place in January.

Richard, 57, appeared before Judge Mark Lucraft QC at the Old Bailey for his first Crown Court hearing.

Wearing a dark grey suit and white shirt with no tie, he spoke only to confirm his name.

Judge Lucraft set a timetable for the case with a plea and case management hearing on November 27 at the Old Bailey.

The trial was provisionally fixed for five days from January 25 2016 at the same court.

Richard, of Islington, north London, was remanded on unconditional bail.

After he was charged last month, Richard issued a statement denying the allegations.

The US-born businessman said at the time: "I absolutely deny the charges against me and will contest this matter in court."

The millionaire, who appeared on the BBC's Dragons' Den in the first two series, reportedly travelled with the Prime Minister on an official government trip to Africa and advised on policy.

His association with Mr Cameron goes back to at least 2008, when the then opposition leader invited the technology entrepreneur to write a report about small business in Britain.

He founded a business loans initiative called School For Startups, alongside the Department for Business, Innovation and Skills.
