Dozens of flights cancelled as thick fog shrouds Britain and brings chaos to airports

Some 85 flights at Heathrow were axed by 10am and there were delays to other departures and arrivals.
Fog also caused disruption at Cardiff Airport. Meanwhile a woman and her dog had to be rescued by the Solent Coastguard after becoming cut off by the rising tide in thick fog on Appley Beach in Ryde, Isle of Wight. Britain was covered in fog this morning as the country prepared for another warm spring day with maximum temperatures of 20C.
