Researching Don Polye

Polye was first elected in 2002 to the National Parliament of Papua New Guinea representing the Kandep Open electorate as a member of the National Alliance Party. He was the Minister for Transport and Civil Aviation from July 2006 to August 2009. Sir Michael Somare, the Prime Minister, appointed Polye to that position in July 2006 as part of a Cabinet reshuffle. He was also Deputy Prime Minister from July 2006 until August 2007. As Minister for Civil Aviation he introduced an "open air" policy ensuring that Air Niugini faced competition from other airlines starting from 2007.

Polye was rushed from a political rally in his Kandep electorate in June 2007 after shots were fired. A rival candidate for his seat was later charged with attempted murder.

Polye was removed from his position as Member of Parliament on 14 August 2009 when the National Court determined that his victory in the 2007 General Election was invalid. The judge's ruling included the observation that it was hard to believe that some polling stations had returned a 100% vote for Polye. The by-election for the seat took place on 9 November 2009, and Polye ran as a candidate. He was successful in regaining his seat.

In July 2010, he replaced Puka Temu as deputy Prime Minister, when the latter tried unsuccessfully to unseat Prime Minister Somare through a parliamentary motion of no confidence. Polye himself was removed as Deputy Prime Minister on 7 December 2010, in an impromptu cabinet reshuffle conducted under what Australia's ABC News called "unusual circumstances". However he was appointed as Papua New Guinea's Foreign Minister later in December 2010, holding that position until another cabinet reshuffle in June 2011. He supported the Opposition when it brought down the government through a parliamentary motion of no confidence in August 2011, and was appointed Minister of Finance by new Prime Minister Peter O'Neill.

In October, the National Alliance Party consequently sought to expel him from the party, but was prevented from doing so by a court order. Later that month, it was reported simultaneously that Polye, along with many others, had been expelled from the party "for conduct prejudicial to the interest of the party", and that he had been elected as party leader. In fact, the party split into factions, one of which was led by Polye. In January 2012, he announced that he was de-registering the National Alliance Party, despite the existence of a rival faction claiming to be the legitimate party. Polye and his faction launched a new party, the Triumph Heritage Empowerment Rural Party ("T.H.E. Party"), ahead of the June 2012 general election.

On 27 February 2012, Prime Minister Peter O'Neill relieved him of the Finance portfolio, taking it on himself, citing "the continuing lack of ability by the department and ministry of finance to contain expenditure overruns outside of the budget appropriations". Polye retained the Treasury portfolio, and gained that of Border Development. Following the results of the 2012 general election Polye retained his position as Treasurer under a new cabinet announced by O'Neill. On 10 March 2014, O'Neill sacked him again, accusing him of having a destabilising effect on the government.

In December 2014, he replaced Belden Namah as Leader of the Opposition to O'Neill's government.
