Delhi Chief Minister Arvind Kejriwal has praised Punjab Congress chief Navjot Sidhu - whose repeated criticism of his own party has made life difficult ahead of next year's election - saying the former cricketer was "raising the public's issues... but Congress is hell-bent on suppressing him". "What Sidhu said yesterday on stage ... I applaud his bravery. (Chief Minister Charanjit) Channi was saying 'I have finished sand mafia in the state and reduced sand prices to Rs. 5 per kg'. Immediately, Sidhu said, 'No... that is a lie. The rate is still Rs. 20'," Mr Kejriwal told reporters.
