Lalu fights for room after blast shuts House New Delhi, Sept. 7: Outside Parliament, Delhi was grappling with a bomb blast, but inside Lalu Prasad was blasting away because he and his MPs did not want to vacate a room already allotted to the Trinamul Congress. The RJD won't let go of room 129 and move to room 125. "Yeh room hum nahi khali karenge. Ladai karenge (we will not vacate this room. We will fight for it)," declared a determined Raghuvansh Prasad Singh, known for high-decibel interventions in the Lok Sabha. After Parliament was adjourned today following news of the Delhi High Court explosion, Lalu Prasad led his MPs to meet Speaker Meira Kumar in her Parliament office. He handed her a petition and argued aggressively in favour of holding on to room 129 that was given to the party in the tenure of UPA I, sources said. "Today, I have just 8 MPs, but tomorrow I will have more MPs," he reportedly told Kumar, to underline that he may need this room in the future. The spacious room 129, which the Trinamul has been allotted because it has 26 MPs, is on the third floor of the Parliament building. When the RJD was allotted the room earlier, its strength was higher than the eight MPs it has now. After Mamata Banerjee's party was given room 129, the RJD was given a smaller one, number 125. "We went yesterday to room 129 under the impression that it was vacant. We found two members of the RJD there and they did not appear to be in a mood to vacate the room. We will take up the matter with the Speaker again," said Trinamul minister of state Sudip Bandyopadhyay. Parliament rules say that a party with a minimum of seven MPs in both Houses is entitled to a room. There are big and small rooms and they are allotted according to the strength of the parties in the Houses. But when dealing with politicians, it's tough to follow the rulebook. "Forcible vacation is not possibleâ€¦. What do you do when some one refuses to make way?" asked a Parliament official. Till Mamata was in Delhi, Trinamul members did not seem too bothered about having the room as the railway minister's chamber served the purpose. With Mamata gone and some MPs not too cosy with her successor, Dinesh Trivedi, the lawmakers felt the need for a room. The RJD has also pointed to railway minister Dinesh Trivedi's room to argue that Trinamul has at least one room to itself but the RJD has none. "Trinamul has six-seven ministers and the railway minister's room is strategically located. Apart from room 129, the RJD has no other room for its MPs to discharge their Parliamentary duties," the petition given to the Speaker said. The matter has put the Speaker in a bind. Kumar has another room problem in her hands. The Telugu Desam has refused to vacate a big room on the ground floor that has been allotted to the DMK. Lalu Prasad has also reminded Trinamul that he had vociferously backed the party when Congress minister Ambika Soni had tried to snatch Trivedi's room. "Now you people should help me," the Bihar leader is learnt to have told some Trinamul MPs. In the past, room 129 had once been allotted to Mayavati's BSP. Lalu Prasad fought and succeeded in keeping the room. "This is the second attack and we are sure Lalu will win again," an RJD MP said, lamenting how Nitish Kumar had ousted them from Bihar and they now have to struggle to keep a room in Delhi.
