An Isis supporter who attempted to create a driverless car bomb is the latest terrorist to plot an attack on the UK after failing to join Isis abroad.

British security services have been heavily criticised for allowing at least 900 men, women and children to leave for Syria and Iraq since 2014.

The flow of jihadis has dried up since the UK and international partners increased efforts to intercept anyone attempting the journey and prosecute them for terror offences.
