Stamp Duty Land Tax (Reduction) Bill

I apologise for intervening on the hon. Gentleman in his good, interesting speech. He said that it is possible for stamp duty purposes to distinguish between a second home and a first home. That means it would clearly be possible to distinguish between second homes and first homes for planning purposes, which would give local authorities the power to ensure that they protect a minimum number of homes for local families. I gave the Government the opportunity just before Christmas to vote for an amendment to do that—why does he think they did not do so?
