The first public hearing into the June 2015 attack in the Tunisian resort of Sousse that killed 38 foreign tourists will begin next month.
A total of 33 people are being prosecuted in the case, including six members of the security forces who are charged with “not assisting people in danger”.
More than 20 months after the massacre, London still advises against non-essential travel to Tunisia, a restriction Tunis would like to see lifted.
The attack was claimed by the Islamic State jihadist group.
