The Intelligence Bureau (IB) is India's internal security and counterintelligence agency under the Ministry of Home Affairs. It was founded in 1887 as the Central Special Branch. The IB is often regarded as the oldest extant intelligence organisation in the world.
Until 1968, it handled both domestic and foreign intelligence after which the Research and Analysis Wing was formed specifically for foreign intelligence; following that, the IB was primarily assigned the role of domestic intelligence and internal security. Tapan Deka is the current director of the IB, since June 2022.
