As Britain ground to a standstill today in Arctic conditions, forecasters gave warning the country should brace itself for six more days of snow. Parts of the country saw 1.5ft (47cm) of snow fall over night and the freezing temperatures are expected to continue for at least another two weeks. Hospitals cancelled operations, schools were closed and the Armed Forces had to be called in to help clear roads. All airports were affected by delays and cancellations. The runway at Gatwick closed with more than 80 flights unable to take off.
