Man stripped of UK citizenship over fears of Paris-style terror attack in London

A Nigerian closely connected to a notorious group of British Islamists has been stripped of his UK citizenship amid fears he would return to London to execute a Paris-style massacre, a court has heard.

The man, known only as L2 for legal reasons, was deemed such a national security threat by Home Secretary Theresa May that she personally signed an order removing his British nationality in 2013, it has emerged.
