died within hours of each other while staying at the Steigenberger Aqua Magic Hotel on Tuesday.
The couple from Burnley, Lancashire, had been on holiday at the resort in Hurghada with their daughter and her three children.
Hundreds of hotel guests have since started to arrive at Manchester Airport after leaving the resort in the wake of the couple‘s death as Thomas Cook launches an investigation.
Several of the have voiced their fury at being “kept in the dark” over what was behind the couple‘s sudden death.
Many have complained about “dozens” of fellow guests falling terribly ill at the hotel, suffering “sickness, diarrhoea and stomach problems”.
One of the tourists, Janette Rawlingson, told ITV News: “They checked all the air conditioning. Dozens were falling ill.
“They were talking about increasing the chlorine for the swimming pool. There were reports the couple had a heart attack.
“But, I think the Egyptian authorities would do anything to protect their tourism.”
Dieter Geiger, General Manager at Aqua Magic, said: “In such a circumstance, very little can be said that will help. This makes it even more important to stick to the facts.
“The doctor’s preliminary report indicates that death was due to natural causes.”
He added that there was no evidence to support an “increased incidence of illness” at the hotel, which he dismissed as “rash speculations”.
Deutsche Hospitality, which oversees the Steigenberger hotel franchise, also released a statement saying they were saddened by the couple‘s deaths.

Mr Harris told Sky News complaints had been made over “the food, the temperatures of the food, things like that”.

said there was no trace of poisonous gas found in the hotel room of the two British tourists.

These findings came after daughter Kelly Ormerod claimed they had been “in perfect health” just hours before they died.
Thomas Cook has said it is “expanding” its investigation and vowed to “get to the bottom” of what caused the sudden deaths
The firm‘s chief executive Peter Frankhauser added that the company had brought in experts to test water, food and air conditioning and the results of the tests should be known within ten days.
The tour operator has said it is “very sorry for any customers whose holidays have been spoiled”.
Mr Fankhauser told Sky News: “We have no real evidence what caused the deaths, but what I can promise is at Thomas Cook we are doing everything to support the family and to support the Egyptian authorities… to get to the bottom of it and to get to the cause.
“There is no evidence that it is a carbon monoxide poisoning. We have no evidence but I don‘t want to rule out anything before I really know the cause.
“Twenty-four hours after the couple died, we had our specialists… in the hotel. They took probes of the food, of the hygienic systems, of water, as well as the air conditioning systems, and all those probes are now in Egypt.
“They are now examining and testing the probes and we support them in doing that, but that takes about 10 days.”
Mr Fankhauser said Thomas Cook decided to move 300 guests out of the hotel 24 hours later as a precaution after becoming aware of an “increased number” of illnesses.
He confirmed that 13 customers had food poisoning but were not in a serious condition.
Mr Cooper, 69, died in his room while Mrs Cooper, 63, a Thomas Cook employee, died after being taken to hospital, according to their daughter Kelly Ormerod.
