Husband and wife terror duo Mohammed Rehman and Sana Ahmed Khan, found guilty of plotting a suicide bomb attack in London, have been sentenced to a minimum 27 and 25 years respectively in prison.

The couple from Reading, who planned a terror attack to coincide with the tenth anniversary of the London 7/7 bombings, were sentenced at the Old Bailey. Rehman, who was also found guilty of possessing an article for terrorist purposes, was sentenced to 12 years to run concurrently for the additional crime.

During preparations to attack either the Westfield shopping centre or the London Underground, Reham, 25, posed questions on Twitter regarding prospective targets under the pseudonym 'Silent Bomber'. He used an image of infamous British Islamic State terrorist Mohammed Emwazi – better known as Jihadi John – to accompany the social media handle.

The Press Association reported that Mr Justice Baker in sentencing remarked that Rehman and Khan posed a significant danger to the public as radicalised extremists. They were expressionless as they were found guilty by unanimous verdict of preparing an act of terrorism.

Prior to the conviction the court heard how Rehman used money from his wife to stockpile explosives at his family home in Reading, and even filmed himself setting off a small explosion in his back garden. The court heard that he was days away from completing the construction of an explosive device that would have caused multiple casualties.

Prosecutors alleged he was "intent on martyrdom" when he tweeted "Now I just make explosives in preparation for kuffar lol and when I've made the required amount I'll be wearing them on my chest", after asking what target to strike.
