CHANDIGARH: Slamming AAP state president, Bhagwant Mann, for speaking blatant lies, Punjab Chief Minister, Captain Amarinder Singh, on Saturday said that it is unfortunate that people like him (Mann), who had no knowledge about the Constitution and legislative procedures, were in politics, and were making illogical statements with the sole motive of misleading the people. The chief minister said that the state government had already finalised requisite petitions for challenging the central Acts and would do so at an opportune time on the advice of legal experts.
