The youngest woman to be convicted of plotting a terror attack on British soil has been jailed for life with a minimum of 13 years.

Safaa Boular, 18, hid her Islamic State-inspired plans in coded conversations about preparations for an innocent Mad Hatter's tea party.

She became the final member of Britain's first all-woman terror cell to be jailed when Judge Mark Dennis QC sentenced her to life imprisonment with a minimum term of 13 years at the Old Bailey on Friday.

Boular was sitting her GCSEs when she was seduced online by IS fighter Naweed Hussain, originally from Coventry.

After she was stopped from joining the 32-year-old in Syria, she discussed a grenade and gun attack on the British Museum instead.

Their plans were uncovered by online MI5 role-players and the Boular family home in Vauxhall, south London, was bugged.

Following a trial, Boular was found guilty of two counts of preparing terrorist acts.
