Terrorists who plotted to bring down aeroplanes after plotting together in Waltham Forest have won challenges in UK's highest court.

Walthamstow man Tanvir Hussain, known as the ‘liquid bomber’ was unlawfully segregated in prison, five Supreme Court Justices have ruled.

The same decision was made over the treatment of Ricin plot conspirator Kamel Bourgass.

After being imprisoned, they were alleged to have intimidated and bullied other inmates over matters of faith, and prison staff considered it necessary to separate them from other prisoners ''for good order and discipline''.

Both men denied accusations that they tried to influence and dictate the beliefs of other prisoners.

In March 2012 the pair failed to persuade appeal judges that their treatment was unlawful.

But, the Supreme Court unanimously ruled today that their segregation was not lawful after initial periods of 72 hours.

The pair had also raised human rights issues - they claimed their rights had been violated - but that aspect of their case was rejected by the Supreme Court.

Hussain, formerly of Nottingham Road in Leyton was one of three men convicted of a plot to launch suicide attacks on flights from Heathrow to America and Canada using liquid bombs made of hydrogen peroxide hidden in soft drink bottles.

He was sentenced to life with a minimum tariff of 32 years in 2009.

During time at HMP Frankland in County Durham from April 24 2010 until October 2010 Hussain was segregated from other prisoners.

Algerian Ricin plot conspirator Kamel Bourgass is serving 17 years for conspiracy to commit public nuisance by using poisons or explosives in relation to the 2002 terror plot.

He is also serving a life sentence for murdering Detective Constable Stephen Oake, 40, with a kitchen knife during his 2003 arrest at a flat in Manchester.

He injured four other officers during that attack and is serving sentences for attempted murder of two officers and wounding a third.
