Though the meeting was summoned to discuss the alleged "raw deal" meted out to Andhra Pradesh in the Union Budget, a speculation was rife that the TDP, the only ally of the saffron party in south India, may walk out of the NDA fold over the BJP's "treatment" to the party.
The TDP and the BJP had contested the 2014 elections in alliance and the BJP has two MPs and five MLAs from Andhra Pradesh.
The YSR Congress also joined the protests in the Well but maintained distance from the TDP members.
According to reports, Singh said that he would convey the feelings of the Andhra Pradesh leaders to Prime Minister Narendra Modi and ensure that their concerns were addressed. "Therefore, the matter they are raising will be looked into", parliamentary affairs Minister Ananth Kumar said.
As soon as the House reassembled after a brief adjournment in the post-lunch session, almost half a dozen TDP members trooped into the Well of the House holding placards "Follow Alliance Dharma", "Keep Your Promises Now" and "Save Andhra Pradesh". The TDP seems to be moving forward in the direction of separating its ways while the BJP is all set to check this unwanted development at a time when its political promptness pulls off a plunge into Karnataka assembly polls.
In a novel protest, one of the members had tied a tuft of his hair with a red ribbon. An MP also brought a "chipli" or "kartal", a musical instrument that chimes, and was also also seen presenting his party's demands by singing a bhajan.
Both houses of Parliament were adjourned soon after proceedings began on Tuesday.
The TDP leader added that Andhra Pradesh was expecting more than the Rs1,330 crore it received for Polavaram, and was hoping for a new railway zone for Visakhapatnam, among other things.
After Question Hour also, Mahajan asked the protesting members to go back to their seats but in vain and also termed their behaviour as "unruly".
