Ranatunga, a minister in the Sri Lankan government, also justified the formation of the committee and said he was ready to help it on matters relating to the game only.
"They are corrupt and just want to continue in power. They are having a gala time clinging on to their posts. So certainly they would not leave their posts voluntarily," Ranatunga, who captained the Lankans to their only World Cuptriumph in 1996, said.
"It's very good decision on the part of the ICC. It seems they have also realised the cricket affairs in the country were in the wrong hands," said Ranatunga, who is the tourism minister in the Lankan government.
Ranatunga said he was hopeful that the present situation would be sorted out soon.
"All are trying to improve things. The interim committee has also contacted me. I will definitely chip in with it if I am asked to."
He said the government was the right choice to handle the game in the country.
"The government should govern all the games in the country since it accountable to the common man, unlike the individual."
