Congress leader Priyanka Gandhi Vadra on Saturday alleged that the BJP-led government is indulging in politics of "suppressing" the unyielding voices of the Opposition, and claimed that the action by probe agencies against Bihar Deputy Chief Minister Tejashwi Yadav was part of this. Her attack on the government came after the Central Bureau of Investigation (CBI) summoned Tejashwi Yadav to appear for questioning in connection with the alleged land-for-jobs scam.
