CCTV footage of the moment a gunman attacked a holiday resort in Tunisia, killing 30 Britons including a couple from Morden, has been shown on the first day of the inquest into their deaths. 

Grandparents Janet, 63, and John Stocker, 74, were holidaying in Sousse when gunman Seifeddine Rezgui opened fire on the beach and around the Imperial Marhaba Hotel on June 26, 2015.

The 23-year-old student killed a total of 38 people using both a gun and a series of explosives before he was killed by security forces. 

CCTV footage showing Rezgui striding along the beach was shown to the court, before panicked tourists were seen running away from their attacker. 

Mr and Mrs Stocker were among the first killed in the terrorist attack. They had been lying on sun loungers in front of the sea. 

CCTV footage was also shown of people fleeing as Reqzui opened fire inside the hotel, killing British tourist Bruce Wilkinson. 

The inquest began with the reading of the names of all 38 victims before a minutes' silence was held in court today, Monday, January 16, at the Royal Courts of Justice. 

Lead counsel to the inquest, Samantha Leek QC, opened proceedings, and said the inquest would focus on the circumstances of the death of each British victim, as well as examining both the travel advice issued by the Foreign Office at the time and the security provisions at the Imperial Marhaba Hotel. 

The actions of Rezgui before and during the attack will also be analysed by the court, including whether his attack could have been prevented or ended earlier. 

Speaking of Rezgui, Ms Leek said: "He systematically took the lives of 38 people who had travelled to Tunisia for enjoyment, luxury and relaxation.

"38 people who had done nothing to provoke this attack, collectively or individually. 38 people who needlessly lost their lives."

Ms Leek said the Metropolitan Police evidence shows Rezgui had been driven to the beach by an unknown accomplice, and proceeded to walk towards the sunbathing holidaymakers carrying a number of explosives and a gun concealed in a parasol. 

Their evidence suggests he killed 20 people on the beach, eight inside the hotel and 10 in the hotel grounds.

The start of the inquest, which was being broadcast live at several court rooms around the country, faced some delays and technical difficulties as the court struggled with video presentations showing the events and timescale of the attack. 

His Honour Judge Nicholas Loraine-Smith will hear evidence specifically relating to the deaths of Mr and Mrs Stocker on Monday, January 23, with the overall inquest expected to last six weeks. 

It will include a mixture of witness statements, CCTV and mobile phone footage of the attack and information from security forces in Britain and Tunisia. 

The friends and family of each victim will also provide a 'pen portrait' to the court to describe their loved ones and the impact their deaths have had on those who knew them.

Mr Stocker was a retired printer and Mrs Stocker worked at the North Cheam branch of Sainsbury’s where colleagues raised money towards a memorial bench in October 2015.

The couple left behind five children and 10 grandchildren.  Speaking on Friday, January 13, their daughter Kelly Stocker-Putt said the family were hoping the inquest would bring a sense of "closure", and that lessons would be learned.
