Kolkata/New Delhi: The Trinamool Congress expects the Congress leadership to keep its "word" on removal of Railway Minister Dinesh Trivedi even as he asserted that Railways is nobody's fiefdom.

The Trinamool Congress sources said that the party supremo and West Bengal Chief Minister Mamata Banerjee is of the view that the Congress leadership and Prime Minister Manmohan Singh have assured her that Trivedi would be replaced with another party nominee Mukul Roy within two days after Friday's presentation of the Union Budget.

They said Mamata has not set any deadline but would like the Railway Minister to be replaced by on Monday.

"I do not want to stick to the ministry. But I also do not want to run away. The Prime Minister has to decide on it (his resignation). There should not be any politics with the ministry. Railway kisi ka jagir nahin hai (the Railways are nobody's fiefdom)." Trivedi told reporters outside his house in the national capital.

Trivedi, who has insisted that Mamata should give it in writing that he should resign, said, "I have high regard for her. She is a good human being."

He said, "I have no problem, I have lot of respect and regard for Mamata Banerjee... She is a great leader and is very much in her right to have her opinion, and I respect her opinion...

"There doesn't have to be everyday communication. I have lots of love and regards for her. This confusion happened if (TMC MP) Sudip Bandopadhyay had not spoken in Parliament... Then things would have been clear. Parliament has its own sanctity," he said.

He said Bandopadhyay had stated in Lok Sabha that the Trinamool has not asked the Railway Minister to resign.

The political spat had got murkier when the party chief whip in Lok Sabha Kalyan Banerjee had asked Trivedi to resign following which the Minister had asked Mamata to give the instruction in writing.
