Calling Karnataka Governor Vajubhai Vala a "stooge of BJP", Congress spokesperson Randeep Surjewala on Wednesday said, "The governor has shamed his office". "By giving 15 days time Governor is encouraging horse-trading by BJP leaders," the JD(S)-Congress alliance's CM candidate, HD Kumaraswamy said. This comes after BJP's BS Yeddyurappa was formally invited to form the government.
