The Press editorial:
Anderton has been weakened, though, by his insistence until now that he would not quit Parliament if he won the mayoralty. He asserted that he could handle both jobs “standing on his head”. It was an assertion that did not go down well before the earthquake and has now been shown to be horribly overweening. Anderton belatedly recognised this with his announcement yesterday that he would in fact relinquish his parliamentary seat if he became mayor. But the concession was made slowly and reluctantly. He had dithered over it long enough for some voters at least to call into question his judgment and temperament for the job.
I’d forgotten that quote that he could do both jobs standing on his head. Anderton has never suffered from a lack of confidence.
