UK security forces slammed for missing London terrorist

 Britain’s security agencies are facing serious questions about why at least one of the London Bridge attackers was known to them but was still able to launch a deadly attack on UK soil. Khuram Butt had been on the radar of the authorities but somehow slipped through the net to lead an attack - alongside Youssef Zaghba and Rachid Redouane- that killed seven people on Saturday and left scores more injured. The issue has become a major election talking point with just days before the polls open with Prime Minister Theresa May promising to toughen up terror laws.
