New Delhi, Dec. 20 :    New Delhi, Dec. 20:  Touched on her raw nerve, Mamata Banerjee today lost her cool in the Lok Sabha and told a BJP legislator that she did not care for the minister's job. She said she could be removed from the post of railway minister if the member had any problem. Trouble erupted late in the night when Tarachand Gehlot, MP from Madhya Pradesh, ticked Mamata off, saying she did not bother about the railways and spent most of her time and energy in West Bengal politics. Participating in the discussion on the railway ministry's demand for supplementary grants for 2000-2001, Gehlot said if Mamata spent more time in the ministry, it would improve the situation of the railways. Angry over Gehlot's remarks, the Trinamul Congress chief said: 'I give more time to the ministry than the party... I have not even gone abroad... If the BJP member has a problem, I can be removed.' Mamata added that every MP visits his constituency. Taken aback by the minister's angry response, Gehlot said he did not mean that she was neglecting the ministry, but that she should spend more time in it.
