UP Minister and former Head of the Close Protection Team (AIG CPT) for the Special Protection Group, Asim Arun, recalled his experiences working with the former Prime Minister on Friday. "The entire country is anguished. I served as Dr Manmohan Singh's main bodyguard for three years, as an AIG Close Protection Group member in SPG. I worked as his shadow for three years and have learnt a lot from Dr Manmohan Singh," he said. Former PM Manmohan Singh (92) took his last breath at AIIMS Delhi after his health deteriorated on Thursday evening.
