Congress on Thursday sought to puncture BJP's campaign on the Lokpal issue alleging that the admission into the partyfold of controversial former U P minister Babu Singh Kushwaha has exposed its probity plank.

Party spokesman Rashid Alvi wondered that on the one hand BJP on Thursday approached the President under the leadership of veteran L K Advani for a strong Lokpal while on the other it has admitted a person like Kushwaha.

A day after he switched loyalties and moved to the BJP, the CBI raided former Mayawati minister Kushwaha. An FIR has been filed against him in the National Rural Health Mission (NRHM) scam.

Amid a row in the BJP over Kushwaha's admission, Alvi insisted that his entry showed what type of the Lokpal the BJP wanted and why it did not cooperate in the passage of the Lokpal Bill in the rajya sabha.

"The true colours of the BJP have come to the fore. All those parties who talked in favour of Lokpal did showed true colour when it came in rajya sabha," he said.

Alvi reminded that while Sushma Swaraj in Lok Sabha repeatedly said that there should not be any haste in passing the Lokpal bill and it should be referred to Standing Committee, the BJP led by Advani meets President demanding a special session to pass Lokpal.

"Whether what Sushma said was right or what Advani-led BJP told the President ?" he asked.

Alvi also utilised the occasion to take potshots at Anna Hazare and Team Anna. He said that there were expectations that the social activist and his colleagues who always train their guns on Congress would target BJP on the Kushwaha issue.

"But not a word was heard about the corruption there."

On reports that Gujarat chief minister Narendra Modi was allegedly misutilsing funds from the communal harmony fund to hold his fasts in different parts of the state, he said that such misutilisation has become tha "habit" of the chief minister.

"Whatever tours he undertake and whatever he does, it will not remove the blots on the chief minister", Alvi said in an obvious reference to the riots in Gujarat a decade back after the Godhra incident.
