Cunliffe and Cosgrove Dog Tucker?

I have spent the day wondering why Clark would call in the Auditor-General and allow him to set his own terms of reference and investigate all matters surrounding the shambles at the Department of Labour and particularly its Immigration Division.

It seems so un-Clark - letting Parliament's designated heavy hitter for anti corruption and independence on a hapless department and potentially her ministry...

I can only conclude she wants current Minister Cosgrove and former Immigration Minister Cunliffe (both from the right of the party) damaged - and probably mortally wounded, so they do not figure in the leadership contests come the blood-letting after the election.

There can be no other reason.
