Flagging the issue, the Haryana Pradesh Congress Committee has written to the Chief Election Commissioner over "breaking news (that) parole will be granted".

It has urged the top poll body that his release from jail at this time would constitute a violation of the Model Code of Conduct in place during elections.

His release has also been red-flagged by the son of a journalist who was murdered, for which Rahim and three others were convicted.

The son said freeing Rahim now "violates democratic values and fair elections" as he could "influence voting by sending messages to benefit a particular party.

Ram Rahim Singh was convicted by a special CBI court in Haryana's Panchkula in August 2017 for raping two women.

Rahim is known to have a mass following in Punjab and Uttar Pradesh, as well as Haryana.

Haryana goes to polling on Saturday in an election seen as being a close contest between the Incumbent BJP with the Congress.
