Trent will be opening its first Star Bazaar in Bangalore on Friday, and the city is expected to have at least six hypermarkets within three years.
In a parallel move, Tata Sons, which has a strategic partnership with Woolworth of Australia, is understood to have put in place a roadmap to launch the supermarket format in India, which will compete with FoodWorld and Spencer's.
