The Greens candidate for the electorate of Melbourne has confirmed he would side with Labor if he wins the seat and the parliament is hung. Despite expressing disappointment about Prime Minister Julia Gillard's positions on climate change and asylum seekers, Greens candidate Adam Bandt yesterday said he would work with Labor to deliver a ''stable, progressive and effective'' government.

''Tony Abbott's conservative positions on many areas, including women's rights, climate change and our rights at work, do not reflect the views of the Melbourne electorate,'' Mr Bandt said. ''It is clear - and I expect the election will confirm - that an overwhelming majority of people in Melbourne do not want an Abbott government.''

According to online betting markets, Mr Bandt is favourite to snatch the seat from Labor. Sportingbet is paying $1.50 for a Bandt win, compared to $2.40 for the Labor candidate, Cath Bowtell, who is taking over from Lindsay Tanner, and $11 for the Liberal candidate, Simon Olsen.

A state-by-state breakdown of opinion polls suggests the election is likely to be close with a hung parliament - requiring Labor to lose between 13 and 16 seats - a growing possibility. That would require Labor do deals with the three independents to get the 76-seat majority needed to govern. So far, the three men - Tony Windsor, Rob Oakeshott and Bob Katter - have been keeping their cards close to their chests.
