On the controversy over the Election Commission allegedly delaying announcement of schedule for Gujarat elections, Yadav told reporters that the body must maintain the role of an "honest referee".
"The decision not to announce elections to Gujarat and Himachal Pradesh simultaneously was not correct...This has happened for the first time.

"They have forgotten their promises and are talking about mandir (temple) and masjid (mosque)," Yadav said, in an apparent reference to alleged communal polarisation.
