.. is the Niira Radia tape controversy.

If you had to read only one article on the issue, it should be this one. Great analysis and meta-analysis:

In all the heat and dust raised by the disclosure of the Radia tapes, the country has been asked to forget something essential: the disclosures and wiretaps are both entirely illegal. The persons now accused of all manner of things were never the subjects of those phonetaps. The purpose of the recorded conversations has nothing at all to do with the uses to which they are now being put. What these tapes do show, and what we are being asked to accept without question is that the government is permitted, even entitled, to illegally curtail our most fundamental civil liberties and that this is not only perfectly all right but is actually necessary.
