Earlier this year Anssi Vanjoki, executive vice-president of Nokia, said at a product show in New York: 'In the mid-Nineties I said that if you don't have a mobile phone you will be making a declaration that you wanted to be outside organised society. People said I was crazy, but now everybody has a mobile phone. Today I'm saying that in 10 years' time the same will be true if you don't have the full internet in your pocket.

A spokesman for Google said: 'We don't comment on market speculation and rumour, but we are focused on mobile and there's nothing new in our commitment to that space.'
