Lengthy queues at Heathrow cleared overnight - but further concerns were raised today about the reputation of the airport with the Olympics on the horizon.
Keith Vaz, chairman of the Home Affairs Select Committee, told BBC Radio 4's Today programme: "There is a real problem and the problem has emerged over the last few months.
"I'm not saying we should abandon checks, but it's a choice for the Government - you either look at the way you deal with people when they arrive at Heathrow or you recruit more staff.
"This is not just about the Olympics, this is about what happens before and after, it's about Heathrow as a world-class airport and it's about our reputation, and we need to make sure we get it sorted."
