Stepping up offensive against SAD, Congress today demanded resignation of Punjab Revenue Minister Bikram Singh Majithia for his alleged involvement in drug racket and termed as "too late" the resignation of Sarwan Singh Phillaur from the Council of Ministers. "The resignation of (Sarwan Singh) Phillaur is too late. We want Bikram Majithia should be made to resign," Punjab Congress Chief Partap Singh Bajwa told reporters here. Phillaur, a cabinet minister, submitted his resignation from the Council of Ministers earlier in the day "on moral grounds" following recent reports of alleged involvement of a family member in drug trade. "During the Lok Sabha elections, the biggest issue that emerged all over the state was the drug smuggling. The menace of drug addiction has hit the youth like epidemic. Drugs and other narcotics are being supplied freely and a strong smuggler-police-politician nexus has developed in Punjab," Bajwa alleged. He demanded that the state government should hand over the investigation into drug racket to CBI. "Now BJP is at the Centre and SAD should have no problem in handing over the drug racket case to CBI," he said.
