I do not know whether the hon. Gentleman has had a chance to look at the briefing note provided by the commissioner's office in the Metropolitan police service. On what it calls the second key area, it states:
''These powers are welcomed by the MPS and we acknowledge the considerable value added to the fight against international crime which these powers permit.''
The key quote is where it goes on to say:
''In the main these are powers with which police officers are familiar and their existing domestic equivalents are well tested within domestic legislation.''
The hon. Gentleman quoted Liberty. Does not he think that the Metropolitan police service may be just as good an authority on this matter as Liberty?
