If the hon. Gentleman will allow me I will answer that by posing a simple question back to him, and then I will give way so that he can answer it. Where will the £12 billion of cuts to welfare come from? How will the £5 billion for tax avoidance be found? If he can answer those questions he will go further than those on his Front Bench have managed to do while making those promises. Perhaps he can shed some light on the issue for the British public.
