Rows continue over immigration queues at Heathrow Operators of Britain's busiest airport are blaming long queues experienced at Heathrow recently on government cutbacks. Rows over border control being too lax have led to closer inspections at the same time the Home Office is reducing border staff by 18 percent over five years. This has meant a waiting time for non-EU citizens of up to 90 minutes. Chaos - complete chaos. We just have too many passengers, too few staff, and a lot of potential problems - public order problems, passenger anger problems, and staff who are knackered to be quite frank," claimed an experienced border control officer who spoke anonymously. Concerned about the travellers coming to the city for the Olympics, London's Mayor Boris Johnson has demanded Heathrow operators BAA stop handing out leaflets pointing the finger at the cuts. Flight disruptions caused by bad weather were the cause of last week's queues, according to the government. More delays are expected this weekend.
