Taxi stunt as Norway's PM Jens Stoltenberg 'struggles in polls'

Norwegian PM Jens Stoltenberg spent an afternoon working incognito as a taxi driver in Oslo, he has revealed.

The footage - made in collaboration with an advertising company - has been posted on the prime minister's Facebook page and made into a film which will be used as part of his campaign for re-election in September.

Norwegian journalist Espen Aas told BBC News that Mr Stoltenberg is struggling in the polls against his Conservative rivals.
