UK FM Johnson: People ask how terrorist slipped through the net

Foreign Secretary Boris Johnson was the first politician from the prime minister Theresa May’s Conservative party to raise questions about the MI5 security service’s failure to prevent the terror attacks plaguing the UK in the past few weeks. "People are understandably right to look at photographs in today's papers of the TV show that this guy was in and to ask what happened, how did this person slip through our net in the way that he seems to have done? MI5 has questions to answer,” he said.
