Prakash, who was legislator from Bawana, resigned from his Assembly and AAP membership in March this year and joined the BJP.
Canvasing support for Ramchandra, who is the party's candidate from Bawana, Kejriwal said Ramchandra's top priority is improving the conditions and solving the water problem in the area.
"There is still time for elections but Ramchandra is taking me to all the lanes. He is asking me to first get the roads fixed rather than thinking about elections. In one month, the construction of roads will start and in three months they will be ready," Kejriwal said.
Kejriwal recently had also interacted with farmers in the area.
