The boss of Red Sea Holidays has written to Theresa May urging her to prioritise an “immediate review” of the ban on flights into Egyptian resort Sharm el Sheikh.

The prime minister is currently in the resort for a Brexit-focused summit with EU leaders.

Sharm has been off limits to flights from the UK since October 2015, when a Russian-operated Metrojet flight was destroyed by a bomb, killing all 224 passengers on board.

The Egyptian State Tourist Office in the UK has long been campaigning for a return of flights to the airport, saying that independent UK security firms have overseen a review into its safety.

Other European countries such as Germany and France have since resumed flights to Sharm, while the UK and Russian governments are yet to sign-off a return to operations.

In his letter to the prime minister, Peter Kearns, executive director of Egypt specialist Red Sea Holidays, wrote: “I write to ask if you would be able to prioritise an immediate review of the current ban on UK aircraft flying into the airport at Sharm El-Sheikh.

“Aside from Russia, the UK is now the only country still maintaining such a ban. During the week that includes the two days of your stay in the city, flight arrivals into Sharm El-Sheikh airport originated from Italy, Belgium, Spain, Poland, Denmark and Switzerland together with 12 other countries.

“As a leading independent British tour operator specialising in holidays in Egypt this request comes with a commercial edge as well as a common sense approach to the global problems caused by such acts as precipitated the current ban, which has now been in place for well over three years.

“I trust your arrival and departure from Sharm El-Sheikh were as trouble-free as all the others during the time you were there.”

Travel Weekly has approached the Prime Minister’s office, and the Foreign and Commonwealth Office (FCO) for comment.
