Dr Julian Lewis: When the Leader of the House has had a chance to check the figures, may we have a statement from her on how much it costs each year to screen letters and packages sent to Ministers and Members of the House for explosive or other hostile devices? Does she agree that it will be possible to save all that money in future if the process becomes redundant – if, for any reason, a comprehensive list of Members' private addresses is ever published on the internet?

[The Leader of the House of Commons (Ms Harriet Harman): I do not want to say too much on the matter of hon. Members' addresses because, as the hon. Gentleman knows, the question whether there is an obligation under the Freedom of Information Act to publicise hon. Members' addresses is before the courts, and they will adjudicate on it. However, I recognise the points that he makes about security, and no doubt those points will be made strongly before the court.]
