Ms Connelly was one of several witnesses to give evidence to Holyrood’s Justice Committee, on Brexit and policing and criminal justice.

She said that as crime had become a global issue, there had been very positive developments in co-operation within the European family to counter the likes of terrorism, counterfeit goods or the sale of untested drugs on the dark web.

“Co-operation has protected citizens of this country, and it is the view of the Faculty of Advocates that harmonisation, co-operation and mutual recognition must continue,” added Ms Connelly.

“In terms of individual members of the public, they may not be aware how this co-operation impacts on their day-to-day lives and their security, but it does and we must ensure it continues post-Brexit.

“Clearly mutual co-operation is in the interests of all countries, but time is of the essence.”
