In a statement issued, the India Ex Servicemen Joint Action Front Sanjha Morcha hit out at Singh, terming him as an "opportunist officer" who always "hungered for publicity and indulged in shamelessly brazen display of rank".
"With his decision to contest the Punjab Assembly elections, the General had not only downgraded the status of the Chief of Army Staff (COAS) but also disgraced the high office of Governor - both positions given to him by the UPA government," said the ex-servicemen group, led by Sanjha Morcha chief patron Lt Gen J S Dhaliwal in a release here.
Meanwhile, Singh today slammed the group for accusing him of entering politics for "petty political gains".
"What political gains? I have joined political party to serve people and people are appreciating my move," the former army chief said this evening.

"Why they are bothered," Singh asked the representatives of the ex-servicemen front, accusing them of being a "motivated group".
He alleged that they are being instigated by Punjab Congress chief Amarinder Singh as they do not have any issue against him.
