A hearing will take place at the Royal Courts of Justice, central London, as the families call for a “full and fearless” investigation into their deaths.

On June 26 2015, Seifeddine Rezgui Yacoubi opened fire at the five-star Rui Imperial Marhaba Hotel and the adjoining beach at the popular resort of Port El Kantaoui.

Thirty-eight people, 30 of whom were Britons, were killed by Yacoubi, who was linked to terrorist cell Ansar al-Sharia.

Families` battles for justice have been intensified by a lengthy and truncated legal process, which had seen the Government apply for certain elements of the inquests to be kept private over concerns about national security.

During a previous hearing Andrew Ritchie QC, representing 20 families, said it was their view that a "full and fearless" investigation would be required to remain in keeping with the principle of "open justice".

Families also claimed they had been assured by tour operator Thomson that it was safe to travel to Tunisia after an attack in March 2015 saw 24 people killed.

The victims were killed in a terror attack at Bardo National Museum in the capital, Tunis.

TUI, the travel company that owns Thomson, said it wants to understand the specific circumstances that led to the killings and is co-operating with the coroner.

The company would not comment further before the inquests but said it does not accept the accuracy of all the statements that have been made.

Mr Ritchie also said many families feared the Foreign and Commonwealth Office (FCO) may have failed in its responsibilities to thousands of British tourists.

He said the families were also potentially concerned about the FCO "having cosy chats" with travel companies interested in running profitable businesses "in light of FCO then current advice that there was a high risk of terrorist activity, including in tourist areas".
