THIRUVANANTHAPURAM: Decks have been cleared for Adani Group to take over the Thiruvananthapuram international airport, but it may have to wait. The Ahmedabad-based group, which had floated the company Adani Trivandrum International Airport Ltd to run the facility, has to see off a slew of litigation. It also has to secure the state support agreement (SSA) from the Kerala Government, which has been strongly opposing the airport’s privatisation.
