A former head of MI5 last night warned the revelations by CIA fugitive Edward Snowden had left Britain at risk of vigilantism because it was less able to protect itself from Islamist fanaticism. <\/p>\n
Breaking his silence on the devastating impact of the security breach, Jonathan Evans said: The result of this can only be that the overall risk of a successful terrorist attack in this country has risen. <\/p>\n
In a chilling intervention, he also warned that events in Syria and Iraq had given jihadis a jolt of energy and the Government must complete the unfinished business of giving the security services extra surveillance powers or risk vigilantism on the streets as citizens look to protect themselves. <\/p>\n
