It was a cool day in the middle of last month when Ratan Tata, 73, the chairman of Tata Sons, the promoter company of the Tata group, India's largest conglomerate, dropped his first bombshell. In a public lecture, Mr Tata described his group's plan in the 1990s to start an airline in India in collaboration with Singapore Airlines.
They went through three governments and three prime ministers for clearance with no avail because, he said, Tata were unwilling to pay a 150 million rupee (Dh12.2m) bribe. Mr Tata's remarks were particularly poignant because JRD Tata, the founder of the Tata Group, began the airline that is now Air India, the state-owned carrier.
Why is Ratan Tata speaking out now? He is hardly the outspoken corporate crusader; his style is quiet and formal and it is without much fanfare that he has raised the fortunes of the group he took charge of in 1991 from an approximately US$2 billion (Dh7.34bn) company to one with revenues of $67.4bn today.
Unlike Mukesh Ambani, the chairman of the giant Reliance Industries, Mr Tata is not flamboyant. He would consider Mr Ambani's $2bn home unnecessarily extravagant. Unlike the Infosys founders Narayana Murthy and Nandan Nilekani, Mr Tata is not easily accessible to the press.
Unlike the younger entrepreneurs who lambast Indian red-tape every chance they get, Mr Tata was never feisty in public. Until recently.
The reticent chairman is going out on a limb these days. He has spoken out against the government several times in the past weeks, calling India a "banana republic", ruing India's poor moral compass and the morass of corruption that is commonplace in the public sector these days.
He has filed a writ petition to India's Supreme Court, seeking that the government probe the leak of taped conversations between him and the corporate lobbyist Nira Radia, in which he and Ms Radia discuss, among other things, the former telecom minister A Raja and Ms Radia's desire to accompany Mr Tata to a black-tie event wearing a Roberto Cavalli dress.
The tapes have provided fodder for much of India's urban elite these past two weeks and now Mr Tata has moved to have them blocked, stating they are an infringement of his right to privacy. Some, however, think that Mr Tata's motives are not so benign.
"What these tapes are doing is that they are unravelling the carefully manicured 'above-the-fray' image that the Tatas have managed to portray in the otherwise messy nexus of big business, big media and big government in India," says Ravi Bapna, a professor at both the University of Minnesota's Carlson School of Management and the Indian School of Business.
Others speculate that Mr Tata's recent outspokenness is prompted by his plans to retire in the near future. "Leaderships mature over tenures," says the brand strategist Harish Bijoor.
"Ratan Tata has moved from being a leader grappling with issues in-house - regional satraps [governors] who headed individual companies following individual styles of governance, to a stage where Mr Tata is being looked up to as one who governs the attitude of Indian business houses at large."
After a spectacular 20-year stint as head of the Tata group, Mr Tata plans to step down in 2012 when he turns 75. A five-member committee has been formed to identify a replacement. The names being bandied about have spent their careers abroad.
Which brings us to the next point: is the Tata group considering leaving India? Is Ratan Tata's growing disenchantment with the Indian business climate an indicator of where the group is headed?
Probably not, because Mr Tata has repeatedly said he would like the group to be an India-based multinational, unlike, say Vedanta or even the Mittal group, which have Indian roots but are based in the UK.
The numbers speak differently though: most of the Tata group's recent and high-profile acquisitions - such as Corus, Jaguar Land Rover, General Chemical, Tetley, Brunner Mond, Daewoo, NatSteel - have been abroad.
The Tata group's revenues for 2009-2010 from its international operations were $38.4bn, which constitutes 57 per cent of its total revenues of $67.4bn. Various companies in the Tata group now depend on international revenues as a significant part of their balance sheet.
Tata Motors reports that its global sales grew 18 per cent in October compared with the same month last year, while sales of the Nano at home, Tata's affordably priced car, are languishing.
The Taj group of hotels, which is owned by Tata, has been buying properties abroad, including the Pierre in New York, the renamed Taj Boston and the Blue in Sydney. Last month, the Tata group donated US$50m to the Harvard Business School where Mr Tata studied. The last move may merely be symbolic but they all point away from India.
Numbers, though, can be read both ways. For every statistic that shows the Tata group's profitability outside India, there are others that point to thriving domestic business, particularly in the core manufacturing sectors.
The most ominous sign, to my mind, is Mr Tata's recent vexation with the Indian business culture. "Ratan Tata is one of the few gentlemen among many industrialists who are crooks and manipulators," says Kishore Mariwala,who spent his career with his family-owned conglomerate The Marico group.
"I am sure he is just fed up, like many other decent citizens of India who are fed up, with the dishonesty and hypocrisy of powers that be."
Perhaps I am reading too much into Mr Tata's remarks but it would be a shame if Tata - both the man and the company - became global instead of local. Tata may not need India but India needs the Tatas.
