Imphal: Former union home secretary Ajay Kumar Bhalla took oath as the 19th governor of Manipur during a function at the Raj Bhavan here Friday.
Bhalla was administered the oath of office by Chief Justice of the High Court of Manipur Justice D Krishnakumar.
He inspected the guard of honour by Manipur Rifles personnel.
Bhalla, who has the rare distinction of being the longest-serving union home secretary, completed his five-year tenure in August last year.
He is a 1984-batch retired Indian Administrative Service (IAS) officer of the Assam-Meghalaya cadre.
President Droupadi Murmu appointed Bhalla the governor of Manipur last month.
Assam Governor Lakshman Prasad Acharya was holding the additional charge of Manipur.
