Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she has made of the potential merits of hypothecating future tax increases to fund specific public services.

It is right that public spending is sustainably funded through a mix of taxes.

The government will ensure that its tax reforms support its wider objectives of making the tax system fairer whilst protecting working people.

The Chancellor will set out tax and spending plans at the Budget on 30 October.
