This is a moderated discussion. We will only be posting a selection of questions, particularly those that are asked by more than one person participating in the chat.

If you really want your question answered, please resend the question after 5-10 minutes instead of sending in a complaint to the moderator.

Not all submitted comments will be published. If you want to share your thoughts on news and politics (and don’t have questions for the guest), please join the discussion at Newsvine.com.
