A JIHADI who plotted to kill jail guards had his human rights breached when put in isolation judges have ruled.

Nadir Syed, 26, blew tens of thousands of pounds of taxpayers’ cash in his legal aid-funded court fight.

And this week, Appeal Court judges ruled Syed’s segregation was unlawful as he was not given a chance to oppose it.

They said his treatment denied him the right to a private life and threatened his physical and mental wellbeing.

Syed was locked up for life in 2015 for buying a kitchen knife to behead a poppy seller.

He later led Muslim inmates in banging on cell doors and threatened to decapitate guards.

Wardens were told not to be alone with him in case he took them hostage.

But he launched his legal fight after being put in isolation at Woodhill jail, Bucks.

He was backed by the High Court in 2017 after claiming he was locked up for more than 21 hours a day.

This week, Appeal Court judges backed the decision, saying it showed “admirable thoroughness and clarity”.
