(Reuters) - The lunch guests were sworn to secrecy.
The European diplomats gathered at the German ambassador's residence in New Delhi's lush green embassy enclave quizzed the guest of honour on everything from the economy and communal violence to his political ambitions. But nobody, the representatives from most of the 28 European Union states agreed, could publicly mention the man they were meeting that day: Narendra Modi, India's most controversial politician and, possibly, the country's next prime minister.
