New Delhi/Kolkata: Following the instructions of his party supremo Mamata Banerjee, Union Railway Minister Dinesh Trivedi finally submitted his resignation. After speaking to Mamata over phone and expressing his willingness to resign from the Union Ministry portfolio, Trivedi declared his resignation, thus ending a four-day fiasco.

Confirming the reports, Trinamool Congress supremo and West Bengal Chief Minister Mamata Banerjee said, "He (Trivedi) called me and he told me that he will abide by the party decision and send his resignation." She also said, Trivedi told him that he will remain with the party.

She further said that the future course of action will be decided in the party parliamentary meeting.

Meanwhile, Trivedi in Delhi told reporters that he called up Mamata to find out the real position. "She was kind enough to tell me (to resign) and as I have a lot of respect for her, I stand by the discipline of the party."

And even before his party chief had reached the national capital to hold discussions on the issue with Prime Minister Manmohan Singh and Congress leaders, Trivedi had put in his papers.

Trivedi's decision came as an anti-climax as he put up a stiff defiance in the last five days, refusing to quit unless asked for specifically in writing by Mamata.

Angered by his budget hiking passenger fares, Mamata wrote to Prime Minister Manmohan Singh on Wednesday night and demanded his replacement with another party nominee and Minister of State for Shipping Mukul Roy.

As she mounted pressure, the Prime Minister and Congress leadership assured her that Trivedi will be replaced in a couple of days after the presentation of general budget on Friday last.
