Discussions between local leaders of JD(S) and Congress had been held twice, Siddaramaiah told reporters here.
Siddaramaiah said BJP leader B S Yeddyurappa, whose son B Y Raghavendra is contesting, forced "this unwanted" by election in Shikaripura following his election as a Lok Sabha member from Shimoga as he aspired to be a union minister.
The Chief Minister visited several villages in the taluk today campaigning in support of Congress candidate Shanthaveerappa Gowda, accompanied by KPCC president G Parameshwara.
Bellary and Chikodi-Sadalga are also going to by-polls.
