The public could be put at risk if the UK leaves the EU in March without an official agreement, the UK’s most senior police officer has said.

Met Commissioner Cressida Dick said a no-deal exit would threaten access to EU-wide criminal databases and make it harder to extradite people from abroad.

She told the BBC the Met was talking to other police forces across Europe about contingency arrangements if needed.

Parliament will vote on the UK’s proposed withdrawal deal next month.

The UK is due to leave the EU on 29 March 2019.
