All cases of arbitrary detention should be pursued at speed from as early as possible with a full mobilisation response before the person is formally charged. We recommend that appropriate consultation take place to establish a clear system for quickly identifying cases that fall under the criteria to be handled by the Director of Arbitrary and Complex Detentions and escalating them to that unit. The FCDO should ensure that it has the in-house capacity and expert capability to negotiate. We recommend that the FCDO prepares advice for families and organisations on the options for engaging a third-party negotiator where the FCDO is unable or unwilling to negotiate with captors, does not recognise the legitimacy of the detaining government, or does not recognise a detention as state hostage taking. The FCDO should constructively work with specialist third-party negotiators and other experts from a very early stage, sharing with affected families as much information as possible.
