The parents of the Muslim convert known as "Jihadi Jack" have denied funding terrorism by sending him money.

John Letts and Sally Lane are accused of sending hundreds of pounds to 20-year-old Jack Letts, who is believed to have joined Islamic State in 2014.

Letts, 56, and Lane, 54, denied three counts of funding terrorism by allegedly sending their son £223 on September 2 last year, £1,000 on December 31 and £500 on January 4.

Lane is also charged with two counts of attempting to send payments of £500 on January 4.

She was not asked to enter pleas on those two counts during a hearing at the Old Bailey.

The couple are due to stand trial at the same court on January 9.

The trial is expected to last up to four weeks.

Jack Letts was suspected of being the first white Briton to join the terror group after he left his Oxford home and travelled to war-ravaged Syria in 2014.

The 20-year-old reportedly goes by the name Abu Mohammed and married an Iraqi woman with whom he has a son, Muhammed.

His parents, of Chilswell Road, Oxford, remain on bail.
