Heavy snow humbles the global elite at Davos summit

The global economy and geopolitical tensions are taking a back seat to a more immediate problem at this year's Davos summit of political and business leaders: heavy snow is burying the venue.Part of the main train line into Davos had been buried in snow over the weekend, forcing people onto buses, and helicopters were disrupted by poor visibility.Businessmen slipped over on icy patches as snow ploughs roamed the streets, with the snow returning as fast as the machines could clear it.
