The trial of the parents of an Oxford Muslim convert known as 'Jihadi Jack' has been delayed.

Jack Letts, 20, is believed to be the first white Briton to have joined so-called Islamic State in Syria, leaving his South Oxford home to join the terror group in the war-ravaged country in 2014.

His parents, John Letts, 55, and Sally Lane, 54, are accused of sending hundreds of pounds to their son between September 2015 and January last year and appeared at the Old Bailey in London today.

The pair, of Chiswell Road in Oxford, have pleaded not guilty to three counts of making money available knowing or having reasonable cause to suspect that it may be used for a terrorist purpose.

Lane is also charged with two further counts of attempting to provide money knowing it may be used to fund terrorism.

The case has been adjourned until Monday.

This morning protestors rallied outside the court building in support of the couple, brandishing signs that read 'families supporting Sally and John', 'imagine if you couldn't help your child' and 'for the love of their child'.

Granting them conditional bail in June, after Mr Letts and Ms Lane were initially remanded in custody, Mr Justice Saunders said they had 'ended up in custody because of the love of their child'.
