Nearly a month of political bargaining could result in a motion of no confidence in the Tongan Prime Minister 'Akilisi Pohiva next week.
Noble MP Lord Vaea says the government has underperformed, particularly when it comes to the budget and changes to the education sector.
Lord Vaea first spoke of a no-confidence motion three weeks ago.
He hasn't officially made a submission but plans to do so next week.
This week the government failed in an attempt to get a two-week adjournment of parliament until some of their MPs returned from overseas.
Mr Pohiva also announced a meeting on education reforms in a last ditch effort to get people on board with the various changes.
Lord Vaea told Koro Vaka'uta the pressure is intensifying.
