LABOR MP Jenny Mikakos will defy Premier John Brumby and lobby the Federal Government for better labelling of genetically modified foods. The move, a direct challenge to Mr Brumby’s authority, comes as caucus dissent erupts over the decision to allow GM canola to be grown in Victoria. Five Labor MPs made anti-GM submissions to a government review, with two yesterday speaking out angrily against Mr Brumby’s decision.
