New Delhi, Jul 29 (IANS): Anna Hazare Sunday began his indefinite fast against corruption at Jantar Mantar, joining other Team Anna members who have been agitating here since July 25.

"He has been fasting since morning," a Team Anna member told IANS.

The members, led by Arvind Kejriwal, began their indefinite fast Wednesday to press for a strong Jan Lokpal Bill and demanding an inquiry into allegations of corruption against over a dozen ministers.

Hazare, 75, had said that he would join the fast from July 29 if the government failed to take immediate steps to check corruption in high places.

His indefinite fast is expected to inject some life into the agitation which has so far received a lukewarm response.

Team Anna has the permission to fast at Jantar Mantar till Aug 8, the day the parliament's monsoon session is expected to begin.

This is Hazare's third indefinite hunger strike demanding a strong Jan Lokpal Bill to check corruption at all levels. His earlier protests led to a nationwide movement.
