Cigarette sales policy's origins sparks debate
Conservative Francis Maude and Labour's Caroline Flint have disagreed over which government was really behind new cigarette sales restrictions in England.
Under the new law tobacco displays in shops will be banned and products kept under-the-counter as part of a package of measures to discourage smoking.
Mr Maude said it was right to bring in the policy, despite Ms Flint saying Tories called it a "nanny-state" idea when the Labour government suggested it.
And Tory backbencher Philip Davies attacked his own coalition government's policy.
