BJP chief Nitin Gadkari on Wednesday lashed out at prime minister Manmohan Singh over the latter's assertion that A Raja was included in the UPA2 cabinet despite the glaring 2G losses he had incurred for the government because of coalition politics.

Gadkari said that being in a coalition did not mean supporting corruption. "This shows the prime minister's helplessness in tackling corruption."

"Coalition dharma cannot mean support to corruption. Even if he used such a feeble excuse to explain away 2G, what is the relation between coalition and the case of ISRO (S-band allocation), Commonwealth Games and Adarsh?" the BJP chief said.

“It is unfortunate that the PM doesn’t have the strength to fight corruption,” he added.

However, Gadkari toned his rehtoric saying that the BJP appreciated trhe prime minister's sese of personal accountability. Singh, earlier in the day, had admitted that mistakes had been made by the UPA government and that he was working to redress these.

But he also added that the government's willingness to curb graft still remained unsatisfactory, highlighting the lost winter session of Parliament in 2010.

"Had they agreed on the joint parliamentary committee probe for the 2G scam earlier, the winter session would not have been lost," he contended.

Gadkari also denied that the BJP had put pressure on the PM over charges faced by a Gujarat minister. The BJP president termed the allegation as "laughable".
