Yes, I think seriously.
Were is your evidence? This is "big time crime". 'Bin diving' is an illegal activity in most, if not all, Western countries.
If you're going to get partisan use the correct term. 'New Labour' under Blair/Brown/Madelson had far too close a relationship with the media 'industry'. This followed on from Thatcher and Major who also had their press secretaries and media friends so there is nothing actually new in that.

The genie is out of the bottle now and, sadly, with Google, Apple, Facebook, et al, constantly demanding more and more information (in exchange for 'essential' services) that would have hither to been considered private we will not re-bottle him/her. It is a dire state of affairs when a subject can have little confidence in the privacy of information within the police services!
The solution is serious jail time and fines for those found guilty and to make the judicial process for individuals less expensive and tortuous. With Cameron's crowd stuffed with the wealthy and Lawyers do you honestly expect anything to change in the near future?
