I attended a London RSA lecture at the RSA last night given by Sir Michael Arthur, formerly our High Commissioner in India. (As an aside I do wish we could call our High Commissioners "Ambassadors" which is what they are; it is silly to continue the High Commission nonsense at the FCO just to placate a crumbling Commonwealth which matters less and less to us every day).
Sir Michael's talk was entitled "Elephants on the Move: How much will India shape the 21st century?" and his answer was as much if not more than China by 2035 which gave us much food for thought.
