Someone should tell David Shearer that getting all indignant about someone else's blunder was not the best of tactics to employ in Parliament yesterday, given that little over a week ago he fessed up to making a rather large blue himself.
Listing an alphabet soup-load of Government entities guilty of similarly serious breaches of privacy - the ACC, MSD and the IRD - the Labour leader wanted to know what the Prime Minister was doing to avoid a repeat of the latest lapse at the Earthquake Commission.
Unable to control his beaming smile, John Key replied that people made mistakes.
Was Shearer saying the staff member at fault at the commission should be sacked? If so, that was a pretty high standard to meet - and one that Shearer had himself failed to meet.
Key was referring to Shearer's strange memory lapse which resulted in him failing to include a $50,000-plus New York bank account in the MPs' register of pecuniary interests.
