Calling for normal functioning of parliament, the Samajwadi Party (SP), the Left parties and the Telugu Desam Party (TDP) said Thursday that a Supreme Court judge should investigate the coal block allocations scam.
The four parties will demonstrate in the Parliament House complex Friday.
"A scam has occurred (in coal block allocation). There should be a probe and the guilty should be punished," SP chief Mulayam Singh Yadav said.
