Former Union Cabinet minister and BJP MP Shatrughan Sinha on Tuesday issued a veiled threat to his party saying "every action has an equal and opposite reaction" even as he refused to react on "unconfirmed and unofficial report" of disciplinary action against him over his recent remarks.

The actor-turned-politician took to micro-blogging site Twitter posting a series of tweets following reports of disciplinary action being contemplated against him over his public statements that are construed as anti-party to some extent.

"After some unofficial news channel reports-and there's nothing official about it -people are seeking my reactions on unconfirmed and unofficial report that BJP will take action after the Bihar elections.I will not comment on unofficial report spread by vested interests," Sinha tweeted on Tuesday.

"However one shouldn't forget Newton's third law "Every action has an equal and opposite reaction"," the Lok Sabha member from Patna Sahib posted next in a veiled warning to his party.

The veteran parliamentarian's latest posts came a day after he tweeted on Monday backing Union Minister and Lok Janshakti Party (LJP) president Ram Vilas Paswan as the chief ministerial candidate of Bihar.

"In my personal capacity and in the larger interest of BJP in general and NDA in particular, I strongly suggest the able, capable, acceptable, respectable and secular Ram Vilas Paswan as the potential / consensus CM candidate of Bihar from our side," Sinha had posted on 24 August supporting Paswan.

"I believe we should have announced our CM candidate. Not putting forward a candidate is a result of some confusion in our own camp. The only desirable and advisable personality from our side who will be acceptable to all of us is Ram Vilas Paswan. The ultimate decision of course lies with the party and its parliamentary board," he had said.

According to reports, a senior BJP leader had on Monday said that the party would not take any action against Sinha till the Bihar Assembly elections were over.

Barely a month ago, Sinha had visited Bihar Chief Minister Nitish Kumar soon after Prime Minister Narendra Modi addressed BJP's Parivartan Rally in Muzaffarpur. Sinha, who was not present in the rally, had praised Nitish Kumar as the "guardian of the state". A day later Sinha had said there was no political angle to his meeting with the JD-U leader and that it was just a courtesy call.

Sinha had also expressed his unhappiness over the suspension of 25 Congress MPs by Lok Sabha Speaker Sumitra Mahajan and was among the around 200 people who had urged President Pranab Mukherjee to reconsider the mercy petition of 1993 Mumbai serial blasts convict Yakub Memon.
