Labour's star performers have had a bad week (or two).
The PM got the facts wrong in her attack on Key.
Cullen has paid too much for the railways, and his overseas investment regulation change looks as though it has breached standing orders.
Goff has a new Defence scandal to control.
King has stuffed up big time over road user charges.
And Shane Jones has caused David Cunliffe huge difficulties by admitting to Cunners knowing more than previously admitted about the former Deputy Secretary of Labour being under investigation (cleverly taking the competition out some are suggesting).
