Senior BJP leader Subramanian Swamy has hit out at 'certain Union Ministers' for meddling with the political affairs in Tamil Nadu as the AIADMK is battling infighting.

However, Swamy refused to name the ministers, who are taking 'undue interest' in ongoing political crisis in AIADMK.

Speaking to India Today, Subramanian Swamy said, "As far as I know Union government has no role to play in governor's stand. But what I heard that there can be certain Union Ministers who are taking undue interest in what's happening in Tamil Nadu. I can't name them."

Swamy's comments follows Union Minister Venkaiah Naidu's remark that 'there is no vacancy' for chief minister's post in Tamil Nadu.

Venkaiah Naidu had said, "Motives cannot be attributed to Governor Vidyasagar Rao as he is discharging his duties as constitutional head of the state in a non-partisan manner," adding, "There is no vacancy to be filled because there already is a government which is headed by a chief minister," Naidu said.

SUBRAMANIAN SWAMY SPEAKS: THINGS TO KNOW I want (AIADMK general secretary) Sasikala to come to Delhi as Chief Minister. Not before that. Sasikala has all the numbers. Yet you guys (journalists) are saying that support for O Panneerselvam is growing. What support some ex-MLAs and few MPs extend to the Chief Minister in Assembly? Even Soli Sorabjee, in an interview to you (India Today), has agreed to the same (that the Governor Rao cannot delay Sasikala's swearing in indefinitely). There is no constitutional crisis, there is a constitutional breakdown in Tamil Nadu. And, that breakdown is because the Governor is refusing to administer oath to Sasikala. Swamy is the first BJP leader to come out in open support of Sasikala while the party and the Centre have backed Tamil Nadu Governor C Vidyasagar Rao's stand to wait till the Supreme Court decides on Sasikala's disproportionate assets case later this week. Meanwhile, an advocate GS Mani has filed an caveat that he should be heard in any matter pertaining to appointment of chief Minister in Tamil Nadu.
