We recommend that a list is prepared of countries where UK nationals face an increased risk of arbitrary detention and being taken hostage. This should inform decisions around the escalation of cases as well as the outward facing travel advice. We recommend that updated FCDO travel advice includes clear criteria, with accompanying explanation, to support an obvious and user-friendly category of “Risk of arbitrary detention”. Moreover, the FCDO should actively brief organisations, businesses and individuals on the risks they face in travelling to these countries and on sensible precautions they can take to mitigate them.
