India's $40bn telecoms corruption scandal

The trial in India's biggest corruption scandal has begun in Delhi with the questioning of the first witnesses.

The scandal involves the alleged selling of mobile phone frequency licences for a fraction of their value.

Former telecoms minister A Raja and MP Kanimozhi are among 14 people from telecoms firms or government who have been charged. All deny any wrongdoing.

Auditors allege the mis-selling of the licences cost the exchequer nearly $40bn (£24.5bn) in lost revenue.
