José Leo, the finance director at BAA, the owner of Heathrow, has admitted he is "very concerned" about border control and security at the official Olympic airport this summer, warning: "It's the weakest link in the chain."
He admitted that BAA was worried that its £20m Olympic investment – including a new temporary terminal for athletes – could be wasted if delays hit its reputation.
"What we see today is not good," he said. "The only positive is that there seems to be a great deal of consciousness about the problem."
Passenger numbers at Heathrow rose 4.4 per cent to a first-quarter record of 15.7 million, with revenues at BAA, which also owns Stansted, up 11.5 per cent to £537m – mainly due to higher spending at airport shops.
