Bengaluru: The Karnataka BJP will lodge a police complaint against Congress Spokesperson Randeep Singh Surjewala for his "baseless allegations" attributed to a diary allegedly belonging to former Chief Minister B S Yeddyurappa, which the I-T department has dismissed as "forgery document".

The Congress had on Friday sought an investigation by the Lokpal into a media report that alleged bribes of Rs 1,800 crore were paid to the BJP top brass by Yeddyurappa.
