The Civil Aviation Ministry on Wednesday signed a memorandum of understanding (MoU) with the Adani group for providing services, including customs, immigration and security, at the Jaipur, Guwahati and Thiruvananthapuram airports, an official statement said.

The Centre had in February 2019 privatised six major airports of the country -- Lucknow, Ahmedabad, Mangaluru, Jaipur, Thiruvananthapuram and Guwahati -- and through a competitive bidding process, the Adani group won the rights to run all of them for 50 years.
