CANBERRA, Australia (AP) — Australia's Parliament elected an opposition lawmaker as its new House of Representatives speaker on Thursday, an unprecedented move that strengthens Prime Minister Julia Gillard's tenuous grip on power because the speaker will not vote in most cases.
The election of Peter Slipper follows the surprise resignation Thursday of speaker Harry Jenkins, a member of Gillard's Labor Party, on Parliament's lasting sitting day of the year and the fourth anniversary of Labor's first election to power. The speaker can only vote to break a tie.
The change effectively gives the center-left government, which nearly lost power in last year's elections, an additional vote in the chamber on most legislation.
Gillard commands 76 seats in the 150-seat chamber with the support of three independent lawmakers plus a legislator from the minor Greens party.
But with Jenkins in the speaker's chair, she had only been able to rely on the support of 75 lawmakers on most votes.
The conservative opposition had been able to muster up to 74 votes, but now can only hope for 73 unless a vote is tied.
Even then, Slipper is unlikely to show loyalty to the Liberal Party, which he defied by accepting the government's nomination as speaker.
Slipper has been a divisive figure in conservative ranks and his own party had already been considering dumping him as its candidate at elections due in 2013.
Opposition leader Tony Abbott had warned that any Liberal who accepted the nomination would be expected to resign from the party.
"The speaker has resigned so that the government can shore up its numbers on the Parliament," Abbott told reporters before the vote. "This is clearly a government in crisis."
Slipper was elected speaker uncontested. Opposition lawmaker Chris Pyne had nominated nine government lawmakers as alternatives, but each declined the nomination.
"It would be the first time in this country's history that the government did not support one of their own to be speaker of this Parliament," Pyne told Parliament as he opposed Slipper's nomination.
Jenkins had been speaker since Labor won control of the government in 2007. But when Labor formed a minority government with the support of independent lawmakers following elections last year, he agreed to bring more independence to the role by dropping out of Labor policy development.
"In this era of minority government, I have progressively become frustrated at this stricture," Jenkins said.
"My desire is to be able to participate in policy and parliamentary debate, and this would be incompatible with continuing in the role of speaker," he added.
