A petition calling for the sacking of the Tonga Prime Minister is to be presented to the King's private secretary at three o'clock today.
The petition, by the Tongan Women's National Congress, is part of a wider protest action, involving prayer and fasting, at what the organisation describes as injustices and poor governance of Dr Feleti Sevele's administration.
The head of the congress, Mele 'Amanaki, says these include the handling of the Princess Ashika disaster and the increasing number of crimes committed by men against women and children.
Ms 'Amanaki is on the fourth day of a hunger strike and says she'll continue without food and water until a caretaker Prime Minister's been appointed.
She says she is experiencing the promise of God in the bible and is feeling stronger than when she was eating and drinking.
Since Monday other congress members have been chain fasting and holding daily prayer meetings.
