17 July 2007 : Column 351W
Norman Baker: To ask the Prime Minister whether it is his policy that no authorisation will be given for the interception of communications in respect of (a) hon. Members and (b) Members of the House of Lords; and if he will make a statement. 
The Prime Minister: I refer the hon. Member to the answer given to him by my predecessor (Mr. Blair) on 27 November 2006, Official Report, column 330W.
