Former chief minister BS Yediyurappa, who is spearheading the BJP's election campaign in Karnataka, today hinted that his son may contest against Congress veteran Siddaramaiah. Siddaramaiah, also a former chief minister, has been fielded from the Varuna seat in Mysuru, currently represented by his son Yathindra. High-level discussions are on to decide if BY Vijayendra will be fielded from Varuna, said Mr Yediyurappa, who is now in a firefighting mode amid protests over reservation issues with the polls just over a month away.
