"There is no link between my continuance in the Railway Standing Committee and UPA coalition. As a senior member of Parliament, the presiding officer has appointed me as Chairman of the Parliamentary Standing Committee on Railways," Baalu said in a statement.
His remarks came a day after Jayalalithaa questioned DMK Chief M Karunanidhi as to why he was silent on Baalu continuing as Railway Committee Chairman and his son M K Alagiri meeting Prime Minister Manmohan Singh and Congress president Sonia Gandhi.
"While the Ministers are appointed by the President, members of the Standing Committees and Consultative Committees are appointed by the presiding officers of Parliament", he said.
Seeking his resignation from the Committee would amount to not only "challenging" the presiding officers powers but also interfering in his Parliamentary rights, Baalu said.
