Question to the HM Treasury:
To ask His Majesty's Government whether they plan to increase the higher rate of income tax to 50 per cent; and, if so, what estimate they have made of the revenue implications of increasing that rate.
The Government remains committed to its manifesto which pledged to protect working people by not increasing rates of income tax.
