Ms Primarolo, your answer to the debate would be so fine that it would hold the rest of us silent.
The hon. Member for Edinburgh East (Sheila Gilmore) is absolutely right. It is difficult to say at exactly what point on the Laffer curve revenue is maximised. As I understand it, however, the latest academic studies suggest that around 37% is the level at which income tax revenues would be maximised. That is why I would favour the Government going further and reducing the rate of income tax to the level at which it was kept by the Labour party when it was in office.
