PC Haldar will take over the reins of the Intelligence Bureau (IB) this month-end from incumbent ESL Narasimhan.
The government cleared Haldar's appointment on Tuesday and is expected to circulate the formal orders on Wednesday. Haldar is a 1970 batch IPS officer of the Bihar cadre. He is reported to have been given a clear two-year tenure.
The UPA government had amended rules to give heads of intelligence agencies a two-year tenure.
Incumbent Narasimhan got one year and 11 months under this provision, apparently to ensure that Haldar remains in the race for the coveted seat. The IB chief is traditionally treated as the senior-most serving police officer in the country.
With the advantage of a two-year tenure, Haldar is expected to carry forward reforms in the country's intelligence machinery to meet the challenges due to the changed tactics of elements inimical to the country.
Haldar, who will turn 60 on January 21, brings to the post experience in VIP security, counter-surveillance and tackling insurgency, especially in the Northeast. He has also served in various missions abroad, including the high commission in Britain.
