Formally launching the Congress signature campaign in the state against the 'black' farm laws, Chief Minister Amarinder Singh on Friday slammed the Shiromani Akali Dal (SAD) for their "political theatrics" over HarsimratKaurBadal's resignation from the Union Cabinet, which they were projecting as a big sacrifice instead of a duty towards Punjab. Recalling that he himself had resigned from Parliament twice to uphold the interests of the state and its people, he said he had done it out of a sense of duty and never as a "sham sacrifice", as had been done by HarsimratKaur. Trashing the SAD protest over the agriculture laws as a "complete failure", Amarinder Singh termed it as an attempt to vitiate the atmosphere of Punjab. "Where were they when the state government moved a resolution in the VidhanSabha on August 28 seeking withdrawal of the anti-farmer ordinances and demanding that the Centre make MSP a statutory right," he asked.
