Ratan Tata, who has died at the age of 86, was a giant of global industry, whose interests included cars, steel, hotels, travel and tea. But he was also hailed as a visionary whose work went far beyond the business world, through his company’s commitment to social causes.

The former Tata Group chairman was seen as a visionary who turned an India-focused family-run business group into a global conglomerate and was admired for his philanthropy.

Crowds of mourners gathered in India's financial capital Mumbai on Thursday for the funeral of industrialist Ratan Tata, hailed as a "titan" who led one of the country's biggest conglomerates.
