Ice and fog cause bring travel chaos to Britain as temperatures plummet to minus 10 Freezing fog brought travel chaos to Britain this morning, with flights cancelled, roads jammed and severe delays on major rail services. Heathrow cancelled between 60 and 70 flights due to the bad weather, while London City Airport was forced to cancel six flights. The coldest spot in the UK last night was Tulloch Bridge in the Highlands where temperatures got as low as -10.2C (13F). Other overnight cold spots included Chesham in Buckinghamshire at -9C (16F) and Little Rissington in Gloucestershire where it was -8C (18F). Forecasters warn that although warmer weather is on its way, it will be accompanied by heavy rain. The worst of the freezing fog lifted earlier this morning, with visibility steadily improving as the day goes on. A Heathrow spokeswoman said: "There have been some delays as well as cancellations. Train travel difficulties continued through the morning. Overhead wire problems between Northampton and Rugby led to buses replacing trains between Northampton and Coventry, while an hourly train shuttle was running between Coventry and Birmingham New Street, with journey times in the area extended by up to 60 minutes. There were also overhead wire problems affecting services in and out of London's King's Cross station. The bad weather disrupted services at Christ's Hospital in Sussex, with trains between Barnham and Horsham delayed. A broken-down train at Melton Mowbray in Leicestershire led to delays of up to 45 minutes between Leicester and Peterborough.
