Deep, crisp and even – some would say the best thing about this year’s World Economic Forum is the quality of the snow on the well-groomed pistes above all the fevered debate.

But one prospective delegate who will not be enjoying them is the United Arab Emirates Oil Minister Mohammed al-Hamli, who has had to cancel his trip to Davos because of a lingering ski injury.

Sources said the minister injured both shoulders in a ski accident during a family holiday in November last year and had to have surgery, which can have only added to the pain of a steep fall in world oil prices.
