Amarjeet Sinha, a senior bureaucrat in the prime minister's office, has resigned from his post, sources said on Monday.
A retired IAS officer, Sinha was an advisor in the PMO and handled projects related to the social sector.
A Bihar cadre IAS officer of the 1983 batch, Sinha had superannuated as rural development secretary in 2019 and was then appointed to the PMO.
He is the second top officer to quit the PMO in recent months after former Cabinet secretary P K Sinha, who worked as principal advisor, resigned in March.
