Mulayam Singh Yadav led a protest at Parliament, demanding a Supreme Court judge supervise an investigation into coal-gate scam. sources in the government say that it is considering whether a judge should review the allocation of coal blocks to private firms.  The manner in which those coal fields were assigned led to windfall benefits in crores of rupees according to the state auditor. The opposition BJP is adamant that the Prime Minister must resign, otherwise it says it will disrupt Parliament as it has for eight days now.  Outside Parliament, Mr Yadav led representatives of the Left and the Telugu Desam Party, stating that the disruption of Parliament must end. In Mr Yadav's call for a judicial inquiry, political parties see a compromise between the BJP and the government which could end the paralysis of Parliament.  Law Minister Salman Khurshid indicated that the government may not be entirely opposed to Mr Yadav's suggestion.
