Efforts to fly home thousands of British holidaymakers stranded in Sharm el-Sheikh were thrown into disarray after an airline announced its flights had been suspended by Egyptian authorities.
While two easyJet planes, due to carry 339 passengers to Luton and Gatwick, were given permission to leave the Red Sea resort, a further eight have been stopped from taking off and are no longer expected to fly today, said the airline in a statement.
The UK Government had been expecting more than 20 flights to bring Britons home over the course of Friday, and Transport Secretary Patrick McLoughlin said it was hoped to clear most of the backlog of passengers by the end of the day.
The Monarch airline said that five planes are currently in the air on the way to pick up Britons from Sharm el-Sheikh and bring them home as scheduled.
The UK government suspended air links on Wednesday after an Airbus 321 operated by Russian airline Metrojet crashed on Saturday, killing 224 people. Militants of the Islamic State terror group in the Sinai Peninsula have claimed that they downed the plane, and Mr McLoughlin said there was now a "high probability" that a bomb in the hold was to blame.
