"This statement effectively means Tonga's King has become a figurehead like the British Monarch."
King George says the monarchy must be an instrument of change and he will now take guidance from the prime minister in all matters of governance save judicial powers.
The King says t the appointment of judges, king's counsel, clemency and commuting prison sentences must be free of political interference.
King George says he will cede some Privy Council functions to cabinet ahead of elections under a new system in 2010.
Once crowned on Friday the King says he will work towards helping Tonga improve its economy through the use of IT and broadband systems.
