Australia's National Party has split from its conservative coalition partner of over 60 years, the Liberal Party, citing policy differences over renewable energy and after a resounding loss at a national election this month.

The move marks a seismic change in the country's political landscape after a federal election that saw Labor win a second term.

Australia's Liberal-National coalition, the country's main political opposition, will split, marking a major shift in the political landscape that comes after the coalition was convincingly beaten by the ruling Labor Party on May 3.
