Polye who was the former Treasury Minister said it was not in the best interest of the country but to satisfy its 'petty bed issues.'
"I needed Hon. Patrick Pruaitch and his lieutenants in July, 2016 when the Opposition moved a Vote of No-Confidence against the Prime Minister.
"Our people have desperately wanted a change in the country's leadership amidst rife in corruption levelled against the executive government, serial breaking of rule of law, embezzlement of public funds and economic mismanagement," Polye said.
Meanwhile, NA Party parliamentary leader Patrick Pruaitch said the decision to leave now is because of the party’s ideology.
“Lot of people will be asking the question why now, as you know National Alliance Party is very supportive of stability in our country.
“We have stayed true to our words (inline) with the Alotau Accord.
“We have remained there until recently when Prime Minister and I have different views in managing the economy,” Pruaitch said yesterday.
NA Party leadership announced the decision to leave the coalition government on Tuesday in Port Moresby, following the sacking of its party leader as the Treasury Ministry by Prime Minister Peter O’Neill last week.
