SYDNEY, Australia - Labor Party leader Kevin Rudd swept to power in Australian elections Saturday, ending an 11-year conservative era and promising major changes to policies on global warming and his country's role in the Iraq war.

The win marked a humiliating end to the career of outgoing Prime Minister John Howard, who became Australia's second-longest serving leader — and who had appeared almost unassailable as little as a year ago.

In a nationally televised concession speech, Howard announced he had phoned Rudd to congratulate him on "a very emphatic victory."

"I accept full responsibility for the Liberal Party campaign, and I therefore accept full responsibility for the coalition's defeat in this election campaign," Howard said.

Howard was also in danger of becoming only the second sitting prime minister in 106 years of federal government to lose his seat in Parliament.

Official figures from the Australian Electoral Commission showed Labor well ahead with more than 60 percent of the ballots counted. An Australian Broadcasting Corp. analysis showed that Labor would get at least 81 places in the 150-seat lower house of Parliament — a clear majority.

ABC radio reported that Howard aides said the prime minister had phoned Rudd to concede defeat. Rudd was expected to formally claim victory later Saturday.

The change in government from Howard's center-right Liberal-National Party coalition to the center-left Labor Party also marks a generational shift for Australia.

Rudd, a 50-year-old former diplomat, urged voters to support him because Howard was out of touch with modern Australia and ill-equipped to deal with new-age issues such as climate change.

Howard campaigned on his economic management, arguing that his government was mostly responsible for 17 years of unbroken growth, and that Rudd could not be trusted to maintain prosperous times.

Rudd said he would withdraw Australia's 550 combat troops from Iraq, leaving twice that number in mostly security roles. Howard had said all the troops will stay as long as needed.

However, a new government is unlikely to mean a major change in Australia's foreign relations, including with the United States — its most important security partner — or with Asia, which is increasingly important for the economy.

But one of the biggest changes will be in Australia's approach to climate change. Rudd has nominated the issue as his top priority, and promises to immediately sign the Kyoto Protocol on greenhouse gas emissions.

When he does so, the United States will stand alone as the only industrialized country not to have signed the pact.

Labor has been out of power for more than a decade, and few in Rudd's team — including him — has any government experience at federal level. His team includes a former rock star — Midnight Oil singer Peter Garrett — and a swag of former union officials.

But analysts say his foreign policy credentials are impeccable, and that he has shown discipline and political skill since his election as Labor leader 11 months ago.

Rudd's election as Labor leader marked the start of Howard's decline in opinion polls, from which he never recovered.

Howard's four straight election victories since 1996 made him one of Australia's most successful politicians. He refused to stand down before this election — even after being urged to do by some party colleagues. However, Howard earlier this year announced plans to retire within about two years if he won the election.
