With all the anger (and rightfully so) over the arrest of Damien Green and his Commons office being searched, some aspects of the case are not being properly considered.
That is, that the civil servant responsible for the leaks is a former Conservative Party member and that there is the allegation that he was used to obtain sensitive information, i.e. that he did not have the idea to leak in the first place. For civil servants to be so politically partisan is as much as a no no in British politics as MP's offices being raided.
If the police had dealt with the case on a softly softly basis and conentrated onthe civil servant alone, then some progress might have been made. They could even have invited Damien Green in for a chat. Perfectly resonable, and then the result could well have been that the Conservatives were caught using civil servants who have political previous to leak government information. This would then have been a disciplinary matter and the Conservatives would have had eggs on their faces.
Make no mistake, we are dealing with an opposition that not only goes for Punch and Judy politics, but appears to absolutely delight in it. They are increasingly fighting low and dirty. Sometimes, if handled well, they get caught red handed, but blundering in heavy handed with little to no respect for the sanctity of Parliament does no one any favours.
