The motion for a vote of no confidence in the Prime Minister of Tonga and his cabinet is being discussed today in the Legislative Assembly.
The opposition Democratic Party has outlined in the motion that in the past 18 months, several matters have arisen which show the untrustworthiness of the Prime Minister, Lord Tu'ivakano, and his leadership.
It says unconstitutional actions have been taken by the Government which have undermined its responsibility to uphold the rule of law.
Radio Tonga reports the motion says changes and the shuffling of some of the cabinet ministers is a sign of an unstable government, and a failure on the Prime Minister's part to unite and organise his cabinet.
It also accuses the Prime Minister of failing to lead and control Tonga's development efforts for the benefit of all the people of Tonga.
The opposition MPs say because of these issues Lord Tu'ivakano should set down and a new prime minister be elected.
An attempt by the opposition to have an urgent vote this morning was defeated.
