Samajwadi Party chief Mulayam Singh Yadav has demanded that Bharatiya Janata Party Member of Parliament Ashok Argal, who made allegations of bribery against his party in the Lok Sabha on Tuesday, be arrested immediately.

"The allegations about bribery is an attempt to defame us," he said.

Union Railway Minister Lalu Prasad Yadav termed the allegation as a 'drama' staged by the saffron party when they were about to be 'exposed for offering money' to RJD's Pappu Yadav.

"It is drama," Lalu told reporters soon after three BJP MPs alleged that they were offered Rs three crore each for abstaining from voting during the confidence motion.

"These (allegations of offering money to BJP MPs) were all false and planted by the opposition parties. Narco-tests should be conducted on the three BJP MPs who leveled the allegations. They should be arrested," he said.

Terming as shameful the alleged bribe offer to three BJP MPs, the Communist Party of India said that the incident highlighted the notorious role of money power in polity.

"It is very shameful. It is a naked display of money power which has brought unmeasureable disrespect to the democracy," CPI national secretary D Raja said.

"This is what the CPI and the Left has been warning about -- the notorious role played by money power in our polity. It is a matter of concern for all political parties," Raja said.

The Bahujan Samaj Party demanded the immediate dismissal of the government.

Speaker Somnath Chatterjee has convened a meeting of leaders from various political parties to discuss the matter.

The Telugu Desam Party said that Prime Minister Manmohan Singh [Images] has a 'moral responsibility' to tell the nation what transpired during the episode.

Noting that his party has been repeatedly saying that the United Progressive Alliance was indulging in horse-trading, TDP chief Chandrababu Naidu [Images] said that the Lok Sabha Speaker should inquire into the incident.
