Heathrow has announced a cap of 100,000 daily passengers throughout the summer and has asked airlines to stop selling summer tickets.

Its CEO, John Holland-Kaye, said the move was necessary because of increased numbers of passengers exceeding the capacity of airlines, airline ground handlers and the airport.
