"A spokesman for Ms Gillard said cabinet confidentiality meant she could not defend herself from the damaging allegations."
I think 'cabinet confidentiality' has now been uttered by Labor more times than 'moving forward'!
Labor have also dug themselves into a hole with this...how will it look if they deny a leak? The first obvious question that will be asked will be WHY they can deny this leak but cannot deny the other ones due to cabinet confidentiality.
