Those looking to use Heathrow Airport this summer as part of their international relocation plans have been warned that London 2012 could cause havoc.
Overseas movers will be looking to use the airport in order to travel to a wide variety of countries and while international removal companies may be able to avoid problems, members of the public may not.
In a letter from the chairman of the House of Commons Culture, Media and Sport Committee, John Whittingdale, to Culture Secretary Jeremy Hunt, he explains his concerns about how Heathrow will cope with the extra workload.
He suggests that while provisions have been made for the staging of the Games themselves, "far less thought seems to have been given to the issue of how to deal with long queues at immigration".
He adds: "The second impact may be that planes cannot unload their passengers into the terminal due to capacity being exceeded. This would lead to circling in the air, planes being left on runways or planes blocking gates."
However, a Border Force spokesperson has said the organisation is well prepared for the Olympics and added that it will have additional staff available for busy periods.
