Johnson: 'I don't know what a pint of milk costs - so what?'

The Mayor of London, Boris Johnson, has admitted that he does not know the price of a pint of milk.

In an interview on Newsnight, Conservative Mr Johnson was questioned about whether he was in touch with the squeeze that people in the country were feeling.

Jeremy Paxman asked the Mayor if he understood that Labour's message about the rising cost of living was striking a chord with voters.
