Vodafone is gearing up to list its Indian business before the end of 2016
Vodafone Group could list its Indian arm earlier than previously expected.
The deal, which is expected to value to the business at as much as at $13bn (£8.7bn), could be completed before the end of the year after reports that Vodafone is likely to file a draft prospectus in August.
Vodafone's India business is the country's largest mobile operator after Bharti Airtel, which operates across Asia.
It was previously thought the telecom giant would list the business early next year.
Vodafone hired Bank of America, India's Kotak Investment Banking, and UBS AG in April as global coordinators for the IPO which is thought could raise $2.5bn.

Analysts have disagreed over the potential value of the business. Bernstein previously estimated its value at $10bn, while Citigroup analysts put it at $13bn.
It was revealed that Vodafone was looking to list the business earlier this year, with Vodafone courting bankers up until April.
Its thought the listing could provide Vodafone with the funds to close the gap with the market leader Bharti Airtel.
