A letter with a motion for a vote of no confidence in Tonga's Prime Minister has been presented to the Speaker of the Tongan Parliament, Lord Lasike.
The Chief Clerk of the House, Sione Tekiteki, says the letter was signed by 'Akilisi Pohiva and the motion for the vote of no Confidence in Lord Tuivakano was signed by some members of parliament.
Mr Tekiteki says Mr Pohiva did not want to reveal who had signed since the motion had not been moved in the House.
Matangi Tonga online says the Speaker informed parliament Tuesday morning of Mr Pohiva's vote of no confidence motion.
But Sione Tekiteki says according to the constitution such a motion "shall not be moved unless at least five working days' notice of the intention to move such a motion has been given to the Speaker."
Meanwhile, the House has started debate on the national budget for 2012-13, and Sione Tekiteki is confident the House will not be dealing with the vote of no confidence until the budget is passed.
The Prime Minister, Lord Tu'ivakano, was elected in December 2010.
