British American Tobacco Australia has launched yet another attack on the Australian government's plain packaging legislation. On top of its latest 'Where's the proof?' campaign, launched today, it is arguing for the legislation to be delayed, calling the proposed timeline 'unworkable'. This comes on the back of one of the tobacco industry’s biggest setbacks: the opposition’s decision last week to support the government’s proposed legislation. This takes Australia a step closer to becoming the first country in the world to implement plain packaging, but it's not a done deal yet.
