This week Four Corners returns in its 50th year with presenter Kerry O'Brien and a new set. The spotlight falls on the nation's leader. Prime Minister Julia Gillard may be instantly recognisable but many Australians say they don't really know her or what she stands for. Some comments have
included:

"I think Julia's as left wing as my right foot.”
"I thought she was pretty hard‐nosed, driven, a bit aggressive and I didn't like her policies.”
"I think she comes from that school of politics that is the art of the possible.”
"I would say she developed a fairly ruthless style. She was tough.”
