BREXIT

Far-right groups could exploit Brexit atmosphere, says counter-terror chief

As for the prospect of a no-deal Brexit, Basu warned it would leave the UK in a "very bad place."

"For counter-terrorism we have a lot of bilateral relationships, it is a devolved power for countries, it is not an EU power, so we are confident that my counterparts in those 27 countries want to exchange information with us and we are working very hard to make sure we put that in place," he said.
"But nevertheless, to leave without... being able to exchange data or biometrics on people who might be criminals or terrorists would be a very bad place for this country, and for Europe, to be," he said.
