Theresa May wants new security treaty with EU next year

“Theresa May is right to warn against letting ideology get in the way of security,” said Sophia Besch of the Centre for European Reform. “But her message should be directed not just at the EU, she needs to say the same to Brexiters at home who categorically oppose the ECJ on ideological grounds.”

May said there could be a legal underpinning to the future security deal that was “respectful of the sovereignty of both the UK and the EU’s legal orders”.

“When participating in EU agencies the UK will respect the remit of the European court of justice. And a principled but pragmatic solution to close legal cooperation will be needed to respect our unique status as a third country with our own sovereign legal order,” she said.
