New Delhi, March 30 :    New Delhi, March 30:  Key BJP allies, the Telugu Desam Party and the Trinamul Congress, vocal critics of the Vajpayee government's handling of the Ayodhya issue and the Gujarat carnage, find themselves in a bind. For Trinamul chief Mamata Banerjee, the growing bonhomie between Ajit Panja and the BJP leadership is a cause for concern. A section of the BJP leadership in league with Panja have not only launched a renewed effort to split her party but also to prevent Mamata's reentry into the Union Cabinet when Prime Minister Atal Bihari Vajpayee expands his council of ministers, possibly after the Budget session of Parliament. Mamata had issued a whip to ensure that Trinamul members, including Ajit Panja, stayed away from the special session on March 26. Sources said Panja consulted parliamentary affairs minister Pramod Mahajan, who told him to ignore the whip, as it did not stand the scrutiny of House rules. The joint sitting over, Panja and two Trinamul MPs attended a dinner hosted by L.K. Advani. The home minister had also ensured that Panja got adequate security to reach the central hall to vote. A large posse of policemen had escorted the Trinamul rebel to Parliament on March 26. BJP leaders are livid that Mamata's party not only stayed away from voting on the terror law in the Lok Sabha but also boycotted the joint sitting of Parliament. As a last ditch effort, Vijay Goel, minister of state in the Prime Minister's Office, had desperately tried to contact Mamata before the joint sitting to plead for her support. Even Opposition parties like the ADMK, NCP and the BSP supported the anti-terror legislation, 'but she had the temerity to oppose such an important piece of legislation for the government', said an NDA leader. Desam chief Chandrababu Naidu's problems are different. With the BJP stock plummeting every passing day, Naidu is seriously considering distancing himself from the saffron party. Sources said Naidu was deliberately going slow on deciding whether the TDP should accept the post of Lok Sabha Speaker. A fortnight ago, Prime Minister A.B. Vajpayee had spoken to Naidu and reminded him of the vacant slot in the Lower House following G.M.C. Balayogi's untimely death. Subsequently, Pramod Mahajan and NDA convenor George Fernandes also spoke to the chief minister, but sources said Naidu was reluctant to accept the post and may continue to support the ruling coalition from outside. Advani was scheduled to go to Visakhapatnam and Hyderabad on March 28 and was supposed to have talks with Naidu. But the home minister cancelled his trip following a 'throat infection'. Reports said Naidu, who had a 45-minute one-to-one meeting with West Bengal chief minister Buddhadev Bhattacharjee, was disinclined to have a one-to-one meeting with Advani.
