The government has forced into retirement 10 senior telecom department officials, some with doubtful integrity, as part of zero tolerance towards corruption. The move follows similar measures taken over the past few years where nearly 400 officers with a dubious track record were removed from government. Union minister Ashwini Vaishnaw approved the forced retirement for 10 senior DoT (Department of Telecom) officials, including a joint secretary, according to an official source.
