Samajwadi Party on Monday warned the ruling United Progressive Alliance that politics of vendetta against leaders of the erstwhile Bharatiya Janata Party-led government, including George Fernandes, would backfire and obliquely criticised the inclusion of tainted ministers in Prime Minister Manmohan Singh's Cabinet.

The SP, having 37 members in the Lok Sabha, also made an implicit attack on the Congress-led coalition saying that though it gave support to the government, they should also have the 'manners while accepting' it.

Despite being a supporting party, not even draft of the Common Minimum Programme was shown to it, SP General Secretary Amar Singh told reporters in Lucknow after a meeting of the party's Parliamentary Board and also that of its Parliamentary Party.

In a significant statement ahead of Parliament session, first of the 14th Lok Sabha, Singh said that his party was 'not captive' to anybody and would praise the Government if it did good work and would not hesitate to criticise if it went astray.

Asked as to what was SP's attitude towards the tainted ministers, he said, "Our view is the same as that of the Left parties."

The Left has criticised the inclusion of tainted ministers Laloo Prasad Yadav and two other members of RJD.

The party came out in support of the National Democratic Alliance convener George Fernandes facing the Tehelka issue and controversies relating to defence purchases, assailing moves of a 'media trial before investigations'.

He said there were innumerable examples right from the days of Emergency to the recent actions of the Punjab Chief Minister Amarinder Singh against his political opponents that showed that vindictive moves prove counterproductive.

Singh's remarks came in the backdrop of Congress leader and Union Minister Kapil Sibal's statement that the inquiry into Tehelka expose during NDA rule should be proceeded with transparency and the Ayodhya demolition case, from which BJP leader L K Advani was 'rescued' by the Central Bureau of Investigation, should be 'put back on the rails'.

The SP had not joined the opposition boycott of Fernandes in the last Lok Sabha when he was the Defence minister.

Singh said the SP, though ruling UP, had not proceeded against Mayawati of the BSP despite she being its known detractor.

The Congress, however, refrained from commenting on Samajwadi Party's caution about the party-led coalition's alleged 'politics of vendetta'.

"I don't know what Samajwadi Party leader Amar Singh has said about Tehelka and Fernandes," party Spokesman Anand Sharma said.

He sought to downplay Singh's criticism of UPA not consulting the SP on the issue of Common Minimum Programme. "It is his view. As far as unity among secular forces are concerned, Congress had taken a principled stand in Uttar Pradesh leading to the installation of Samajwadi Party-led government in the state. We decided to support it from outside and that support is still on," Sharma said.

He also reminded Samajwadi Party leader that even though Left parties were supporting the United Progressive Alliance from outside they are 'integral part' of the coalition.

However, Sharma said the party would welcome suggestions from progressive and secular forces to strengthen the coalition.
