Vanimo Green MP Belden Namah publicly apologised to Grand Chief Sir Michael Somare for what transpired during the political impasse in August 2, 2011.
He said Sir Michael was a true father that always had a forgiving heart for his children.
Namah said what transpired was politics and nothing personnel.
Deputy Opposition Leader Sam Basil also apologised to Sir Michael for what they had done in 2011.
He said they realised that they did make a mistake with their actions in forcefully removing Sir Michael.
Basil also publicly apologised to Sir Michael in Wewak during Sir Michael’s 80th Birthday anniversary in March.
The political impasse in August 2011 began when the Speaker of Parliament accepted the Opposition's claims that the prime ministership was vacant.
At the time, Sir Michael Somare - who had been elected prime minister in 2007 - had been out of the country for several months while undergoing medical treatment in Singapore.
Belden Namah was then Opposition Leader along with his deputy Sam Basil.
Accordingly, Parliament elected a new prime minister in Peter O'Neill.
O'Neill's initial parliamentary majority of 70 to 24 - included many former members of the coalition previously put together and led by Somare.
Other members have subsequently changed sides.
In December 2011, the Supreme Court found that Somare was still legally prime minister.
Parliament responded by withdrawing the leave on which Somare had relied while he was out of the country and re-elected O'Neill.
It also passed a new law preventing a person aged 72 or older from becoming prime minister.
As Somare was already 75, the new law - if it is constitutional - makes him ineligible to return as prime minister.
The nation underwent some very trying moments and held its breath as one crisis after another unfolded and continued infighting and political maneuvering and countless court actions piled up against the two political groups.
The Police was divided, as well as the Defence Force and there was an event of a possible military coup and mutiny, followed by a police mutiny and public demonstrations funded by the various interest parties, while all along the clock ticked to a countdown to the looming National General Elections for 2012.
The People’s National Congress Party won 27 seats in 2012 General Elections and was invited by the Governor General to form Government.
The 9th Parliament was formed and Peter O'Neill was once again elected Prime Minister through the mastering of more candidates and been the largest political party with more members to win the national general elections of 2012.
Since then O’Neill has been running the affairs of the country as the prime minister.
Even though he has been implicated by some serious allegations, O’Neill has always used his numerical strength in government and the courts to seek refuge.
After three attempts by the Opposition to table the vote of no confidence against O’Neill have been in vain, the Supreme Court last Tuesday ordered the recall of Parliament to deliberate on the motion.
The Parliament met last Friday (July 15) and introduced the motion as per the court order.
Parliament then adjourned for seven days and will resume this Friday (July 22) for deliberation and for a vote to be taken against Prime Minister Peter O’Neill.
Currently both sides of the house are in camps with both claiming to form the next government.
The Friday session of Parliament will reveal the numbers.
