CANBERRA, Australia (AP) — Prime Minister Tony Abbott has reintroduced legislation to the Australian Parliament that would repeal a carbon tax that the nation’s worst greenhouse gas polluters have to pay.

The opposition center-left Labor Party and minor Greens party used their Senate majority in March to block the bills to remove the tax, which was introduced by a Labor government in July 2012.

But with new senators taking their seats on July 7 for the first time since Abbott’s conservative coalition government won elections in September, the bills are expected to be passed by a narrow margin.

While introducing the bills to the House of Representatives where the government holds a clear majority, Abbott said on Monday that voters had rejected the tax by electing his government.
