What are the toughest questions you'd like me to ask Michael Howard about Britain's aid budget?

Later this month I'll be interviewing Michael Howard at an event for Conservatives for International Development. Lord Howard has been a prominent supporter of the Conservative commitment to spend 0.7% of national income on international development. It was under his leadership that the party first made a commitment to hit the UN aid target by 2013.

I want to put the toughest questions to him and I know many ConHome readers are sceptical about the aid budget. Please help me, therefore, pose the most searching questions and if you cannot attend the central London event yourself I promise to report back with his answers...
