The government said on Monday it plans to sell its entire interest in Air India Ltd, in a renewed push to sell the airline after an attempt to auction a majority stake almost two years ago failed to draw any bids. Substantial ownership and effective control of the airline must remain with an Indian entity, the government also said. The potential sale of an airline kept aloft by a $4.2 billion 10-year bailout in 2012 comes as the government divests of money-losing assets to manage the fiscal deficit.
