BJP president Nitin Gadkari, who had recently asked Karnataka Chief Minister BS Yeddyurappa to call off his 'temple truth test', has defended the Chief Minister against a series of corruption allegations. Speaking to NDTV's Barkha Dutt, Gadkari said Yeddyurappa has done nothing illegal. He, however, added that Yeddyurappa should not have used his discretionary quota for his family members.
