Dalmiya and Ganguly have long been seen as allies

Former captain Sourav Ganguly has called for a probe into the leaked e-mail that ended his India career.

The move, during Cricket Association of Bengal (CAB) elections, has been taken as a threat to former India cricket board supremo Jagmohan Dalmiya.

Coach Greg Chappell's e-mail, which said Ganguly was no longer fit to be captain, was made public in September.

Ganguly told Dalmiya's election rival, Prasun Mukherjee, the person who leaked the e-mail should be punished.

The call was seen by many as a hint that Dalmiya was the man behind the leak.

Sourav's e-mail hints that he indirectly supports me Prasun Mukherjee Dalmiya's election rival

Mukherjee, Calcutta's police commissioner, is running for the CAB presidency against Dalmiya, who has held the post for more than 15 years.

Elections take place on 30 July.

During his time as president of India's national cricket board, and at the helm of the International Cricket Council, Dalmiya was seen as a close ally of Ganguly.

Ganguly, India's most successful Test captain ever, was deposed after the arrival of Chappell as coach last year.

Currently playing county cricket with Northamptonshire, Ganguly contacted Mukherjee via e-mail this week.

"Sourav's e-mail hints that he indirectly supports me. Also many people in the local association want change in the local association this year," Mukherjee told the BBC.

Dalmiya declined to comment on this issue when contacted.

However, he told the BBC he has decided to fight the election after being overwhelmed by the goodwill of members.
