Thousands gather in Canberra for carbon tax protest

Thousands of people gathered in the Australian capital, Canberra, to protest against a planned carbon tax aimed at curbing greenhouse emissions.

It is the centrepiece of Prime Minister Julia Gillard's environmental strategy, despite her ruling out its introduction during last year's election campaign.

A year on from that pledge, conservative opponents, who opposed the measure, are calling for new elections.

They say the tax will drive up household bills and cost jobs.
