The campaigning for elections to the 272 wards of three municipal corporations will end on April 21 evening but the schedules for the two leaders are yet to be finalised.
The two "youth icons", as many party candidates believe them to be, are in "heavy demand", especially among young candidates to canvass support for them in their wards, said a senior Delhi BJP leader.
The two are among the list of star campaigners but their schedules have not been finalised, party spokesman Navin Kumar said.
Most of the star campaigners are likely to come to the national capital beginning from April 19 and Yogi and Fadnavis are also expected to participate in it, they said.
"We are trying to arrange visits of all the star campaigners including CMs Adityanath and Fadnavis. So far, approval from Union Home Minister Rajnath Singh and BJP president Amit Shah has been received," Kumar said.
The BJP is pitted against Congress and Aam Aadmi Party in a triangular contest in three municipal corporations.
