Yunus is celebrated worldwide after winning the 2006 Nobel peace prize for Grameen's much-copied microfinance scheme that provides small loans to millions of poor people, but he has fallen out badly with the Bangladeshi leader.

Grameen Bank was recently cleared after a Norwegian documentary accused it of financial wrongdoing, but Hasina has since accused Yunus of pulling a "trick" to avoid tax and said microfinance loans were "sucking blood from the poor".

Hasina, who also accused Yunus of turning Grameen Bank into his own private fiefdom, first clashed with Bangladesh's "banker to the poor" in 2007 when he set up his own short-lived political party.

A five-member committee would look into the documentary's allegations that 96 million dollars was illegally diverted from Grameen Bank to other parts of Grameen group, Bakul Chad Das, a senior government official, told AFP.

"The committee has been given three months to complete its task, which also includes reviewing Grameen Bank's lending rate compared to other micro-lenders," he said.

The probe into Grameen comes as the microfinance industry is under fire in neighbouring India over accusations of profiteering through high interest rates and heavy-handed debt collection.

"The review is not directed against any person," the head of the government's review body, A.K.M Monowaruddin Ahmed, told AFP.

"We are to review the total operations of Grameen Bank, its lending and its interactions with its sister organisations."
