88. The Parties recognise the value in facilitating operational cooperation between the United Kingdom’s and Member States’ law enforcement and judicial authorities, and will therefore work together to identify the terms for the United Kingdom’s cooperation via Europol and Eurojust. 89. The Parties should establish effective arrangements based on streamlined procedures and time limits enabling the United Kingdom and Member States to surrender suspected and convicted persons efficiently and expeditiously, with the possibilities to waive the requirement of double criminality, and to determine the applicability of these arrangements to own nationals and for political offences. 90. The Parties should consider further arrangements appropriate to the United Kingdom's future status for practical cooperation between law enforcement authorities, and between judicial authorities in criminal matters, such as joint investigation teams, with the view to delivering capabilities that, in so far as is technically and legally possible, and considered necessary and in both Parties’ interests, approximate those enabled by relevant Union mechanisms.
