Chandigarh, July 28 -- The Opposition on Monday stepped up their attacks on Punjab chief minister Bhagwant Mann, health minister Dr Balbir Singh and education minister Harjot Singh Bains over alleged paper leaks and irregularities in recruitment examinations in the state, a charge denied by the AAP government.

Shiromani Akali Dal (SAD) MP Harsimrat Kaur Badal demanded an inquiry by a sitting judge of the Punjab and Haryana high court into the pharmacy officer recruitment exam irregularities. Earlier, SAD and its youth wings staged a protest outside the main gate of Faridkot-based Baba Farid University of Health Sciences, demanding the cancellation of the pharmacy officer recruitment examination, alleging it was leaked in an organised manner. BJP leader Tarun Chugh sought a CBI probe into the alleged cheating racket, which he alleged had exposed the "double standards" of the AAP leadership. Denying any paper leak in Punjab, AAP national convener Arvind Kejriwal accused the BJP of trying to tarnish Punjab's transformation from 27th to number one in the country's education rankings under the AAP government.

Health minister Dr Balbir Singh termed Opposition allegations as false propaganda and politically motivated misinformation....
