After his return from the aerial survey, Singh, accompanied by a high-level delegation of experts, was scheduled to hold meetings with Chief Minister Tarun Gogoi, his Cabinet colleagues and senior government officials at the Gopinath Bordoloi International airport.

Gogoi, who was expected to accompany the prime minister during the aerial surey, was unable to do so as he is indisposed.

Singh was earlier received at the airport by Assam's Governor Lt Gen (Retd) Ajai Singh, Gogoi and his senior Cabinet colleagues.

The prime minister was also scheduled to meet representatives of different political parties and organisations and address the media before his return to New Delhi in the afternoon.

This is Singh's first visit to Assam, which he represents in the Rajya Sabha, after becoming the prime minister.
