As the UPA managers continued to woo smaller parties, the one-MP strong National Loktantrik Party (NLP) on Thursday announced that it will vote against the government during the trust vote even as Samajwadi Party claimed the support of its lone member in favour of the ruling coalition.

NLP president Arshad Khan said his party would issue a whip to its MP Baleshwar Yadav to vote against the government on July 22 in the Lok Sabha as it was opposed to the nuclear deal with the United States.

Yadav, who quit Samajwadi Party earlier, is the NLP MP from Padrauna (UP) Lok Sabha constituency.

"Prime Minister (Manmohan Singh [Images]) has explained the deal to SP leaders Mulayam Singh Yadav and Amar Singh only. He should explain it in detail to other parties also," he told reporters.

After submitting a fresh letter to President Pratiba Patil vowing support to the UPA, Singh has claimed on July 9 that the NLP MP would vote in favour of the UPA. "Baleshwar Yadav is basically of Samajwadi Party origin," Singh has said.
