'No-deal Brexit risks UK security'
A former head of the UK Foreign Office, Lord Ricketts, has warned that if the UK leaves the EU without a deal, law enforcement and judicial cooperation will be severely affected.
He told Hardtalk's Stephen Sackur: "We believe there are real risks for our security of leaving the EU without tying down a continuation of the co-operation that goes on under the EU instruments.
"At the moment our police forces depend upon databases, on confidential messaging systems, on a whole range of instruments to co-operate across borders with their European counterparts."
Lord Ricketts was also the first UK National Security Adviser under former Prime Minister David Cameron.
