A few days ago, India's Election Commission released updated draft electoral rolls for Bihar state, where key elections are scheduled for November, following a month-long revision of the voters' list.

But opposition parties and election charities say the exercise was rushed through - and many voters in Bihar have told the BBC that the draft rolls have wrong photos and include dead people.

The Special Intensive Revision - better known by its acronym SIR - was held from 25 June to 26 July and the commission said its officials visited each of the state's listed 78.9 million voters to verify their details. It said the last such revision was in 2003 and an update was necessary.

The new draft rolls have 72.4 million names - 6.5 million fewer than before. The commission says deletions include 2.2 million dead, 700,000 enrolled more than once and 3.6 million who have migrated from the state.

Corrections are open until 1 September, with over 165,000 applications received. A similar review will be conducted nationwide to verify nearly a billion voters.
