In a resolute move, Aam Aadmi Party (AAP) MP Raghav Chadha has written a letter to Rajya Sabha Chairman Jagdeep Dhankhar, urging him to block the introduction of a contentious bill aimed at replacing the Centre's ordinance on control over administrative services in Delhi. Terming the bill as "blatantly unconstitutional," Chadha raises concerns over the government's attempt to undermine the Constitution and strip the elected Delhi government of its governing apparatus.
