The announcement came after coroner Judge Nicholas Loraine-Smith rejected calls from some relatives to rule that neglect by Tui or the owners of the Riu Imperial Marhaba Hotel in Sousse played a role in the deaths.

Kylie Hutchison, from solicitors Irwin Mitchell, confirmed in a statement on behalf of the families that they would be taking legal action against Tui.

“On behalf of our clients who lost members of their family and those who suffered in this terrible incident, we will now be preparing to commence civil proceedings against Tui for damages.

"Further submissions will now also be made to the coroner aimed at preventing future deaths."

Nick Longman, Tui UK’s managing director, said outside the court: “We will deal with the civil case as and when it arises.”

Longman also read out a statement following the outcome of the inquest.

“We have now heard the coroner’s findings and his comments regarding the provision of security and visibility of travel advice,” he said.

“These are complex matters and we have already taken steps to raise awareness of the FCO’s Travel Aware campaign. Together with the travel industry in light of these comments we must now take some time to further reflect on these areas.

“On that day the world changed. As an industry we have adapted and we will need to continue to do so. This terrorist incident has left its mark on all of us and its impact will always be remembered.”
