The decision to this effect was taken at a meeting of office bearers of CPIM, CPI and CPI (ML-Liberation) here.
The meeting discussed issues like reported misuse of official power by Rajasthan Chief Minister Vasundhara Raje and External Affairs minister Sushma Swaraj in the wake of former IPL boss Lalit Modi's revelations, Vyapam scam in Madhya Pradesh and death of 47 persons related to it, PDS issue in Chattisgarh, besides the scam in Maharashtra involving two ministers, V Ramamurthi, District CPI(M) president, said.
The parties would demand a Supreme Court monitored probe in all these scams and to bring to book the culprits and punish them, Ramamurthi said.
