TUI has been slapped with a second lawsuit from no-win, no-fee solicitors after a further 16 guests staying in the Egyptian resort of Hurghada say they were struck down with stomach bugs.

The guests had all stayed at the five-star Jaz Bluemarine hotel between February and August 2019.

The law firm Irwin Mitchell had already started court proceedings against TUI on behalf of 36 guests who had stayed at the Jaz Aquamarine hotel, a sister property to the Bluemarine, between February and August 2019. Guests are able to use the facilities of both hotels, which sit back-to-back.

A spokesperson for Irwin Mitchell said the claimants are all seeking compensation ‘for the illnesses they suffered’.

TUI said in a statement: “We are sorry to hear of these experiences at the Jaz Aquamarine Hotel.

“As this is now a legal matter, it would be inappropriate to comment further at this time.

“We’d like to reassure customers that we regularly audit all of our hotels in respect to health and safety, including hygiene.”

Jet2holidays is also being investigated by Irwin Mitchell after more than 140 holidaymakers who stayed at the five-star Mukarnas Resort and Spa in the Turkish resort of Antalya say they fell ill.

The guests, who travelled in May 2019, allegedly suffered symptoms which included stomach-ache, vomiting and diarrhoea. A family of four told Irwin Mitchell they had all become ill within days of arriving at the resort, and the mother and son were still suffering from symptoms months after their return to the UK.

Irwin Mitchell said: “We now represent more than 140 people who stayed at the Mukarnas Resort and Spa this summer and understandably have many questions about how they fell ill. We’re now investigating their concerns and are determined to obtain the answers they deserve.”

In a statement, Jet2holidays said: “We are sorry to hear about any customers feeling unwell. As lawyers have been instructed, it would be inappropriate for us to make any further comment at this time.”
