Criticism of government plans to give the police and MI5 powers to read private e-mails has been mounting. The British Chambers of Commerce warned that the bill regulating investigatory powers would jeopardise online deals by compromising confidentiality. And companies losing business if information is leaked as a result will not be offered compensation under the existing plans. The Alliance for Electronic Business, which includes the Confederation of British Industry, has also criticised the bill. The legislation, designed to help police track internet criminals, is due to be considered by a parliamentary committee next week.
