The arrest of former Karnataka chief minister B S Yeddyurappa would not cast a shadow on L K Advani's yatra against corruption, the BJP said today. "Our party has given a message that we do what we say. In Yeddyurappa's matter, our president Nitin Gadkari had announced a change after Lokayukta's report and it has been done," BJP's national General Secretary Vijay Goel said.
