Dunedin's deputy mayor Sophie Barker has resigned, saying the breach of a confidential council meeting was the final straw. Just days ago, she and senior city councillor Jim O'Malley filed a complaint about Mayor Jules Radich, for minimising a racist outburst by community board chairman Barry Williams. Barker will continue on as a councillor. Radich has accepted her resignation and RNZ has contacted the Mayor for comment. Sophie Barker was not available for an interview today, but councillor Jim O'Malley spoke to Charlie Dreaver.
