I do not think that our plans do. We would look at mansions—that form of housing accommodation. However, I would be prepared to see whether the Treasury study, which could be commissioned under the new clause, could look at whether farmhouses would be ruled out. We would be happy to look at such questions. We should, however, be looking at personal estates of £2 million and more in that built-mansion context. That is the nature of the proposition before us. In clause 97 and beyond, definitions of property are set out in respect of the annual tax on envelope dwellings. They provide a series of exemptions and set out where the line should be drawn in terms of farmhouses and so forth. I recommend those clauses to the hon. Gentleman, as they may well serve as a guide as to how a mansion tax could work in future.
We need that work to be undertaken, however. This new clause does not seek instantly to implement the Liberal Democrat proposition. It simply seeks to find ways of building on that as a basis on which to look at the annual tax on envelope dwellings, thinking of how that might apply to a mansion tax, and in particular using that revenue to help 25 million basic rate taxpayers.
That is the objective. We have got to give more help to those who are finding it difficult to make ends meet. That is why I commend this new clause to the House.
Question put, That the clause be read a Second time.
