Julia Gillard, the Australian PM, is a liar and a cheat.

This government’s carbon tax policy is released and Andrew Bolt eviscerates it:
‘…Julia Gillard cites in her support Margaret Thatcher, who indeed did warn in 1988 that we should worry about global warming. What Gillard fails to add was that by 2002, Thatcher had developed second thoughts about the alarmists, writing that global warming “provides a marvelous excuse for worldwide, supra-national socialism”…’ (bold mine. kg)
