New Delhi: Differences between the promoters of the country’s largest airline IndiGo came into public on Tuesday with Rakesh Gangwal alleging serious governance lapses by co-founder Rahul Bhatia who had earlier termed his demands as unreasonable. With the issues brewing for nearly a year, Gangwal has sought markets regulator Sebi’s intervention to address the problems. In a filing to the stock exchanges, InterGlobe Aviation, the parent form of IndiGo, said its board of directors has received a letter from Gangwal and Sebi has also sought a response on the letter.

Alleging that the company has “started veering off” from the core principles and values of governance, Gangwal has said that even a “paan ki dukaan” (betel shop) would have managed matters with more grace.

Gangwal and his affiliates have around 37 per cent stake in InterGlobe Aviation while Bhatia and his affiliates (IGE Group) have about 38 per cent.
