Sorry, all the knives are in other people's backs

Prime Minister Julia Gillard, Opposition Leader Tony Abbott, and government backbencher Kevin Rudd faced off last night in one of the political year's most eagerly-anticipated battles: whose item in the Parliamentary Midwinter Ball auction would earn the highest bids?

The winner was Tony Abbott, whose barbecue for eight top-scored with $11,100.

The PM came in equal second, her dinner for four at the Lodge in a tie with dinner with the former PM, at $10,100.

All three auctions were won by activist group Walk Free, which seeks to draw attention to human trafficking within Australia.

The group has since announced that in the interests of fairness, it would pay $11,100 to all three MPs' designated charities.

We're assuming that you HAVE to bid. You can't get out of it. Them's the rules. Go on, it's for a hypothetical charity.
