Act Leader John Banks yesterday jumped at the chance of payback against David Shearer, demanding the Labour leader stand down over his "secret" United States bank account.
Mr Shearer strongly criticised Mr Banks last year over the Act leader's failure to remember receiving a political donation from internet tycoon Kim Dotcom and called for Prime Minister John Key to strip him of his ministerial portfolios.
Yesterday, the boot was on the other foot as Mr Shearer admitted he had forgotten to include details of a US bank account containing more than $50,000 cash when filling in his register of pecuniary interest form. Mr Shearer acknowledged he'd made the mistake during each of the preceding three years.
Mr Banks said Mr Shearer was on record as saying that anyone with a memory lapse was not fit for public office and should stand down.
"Yesterday he told us he for9got not once but on four occasions to tell the Parliament about his secret US bank account. He didn't forget to tell the IRD about this secret bank account but he forgot to tell the Parliament, he had a memory lapse.
