Kishanganj (Bihar), Oct 10 - BJP today accused the UPA government of "misusing" the CBI to coerce Mulayam Singh Yadav and Mayawati to continue supporting it from outside. The party asked the two leaders to explain reasons for supporting a "scam-tainted" government at the Centre. "It is obvious that the UPA government is dangling the sword of the CBI probe against Mulayam and Mayawati into corruption charges against them to coerce them to support it," BJP spokesperson Syed Shahanwaz Hussain told reporters here.
