"It seems BJP, just like the previous Congress government, has a nexus with power discoms, that is the reason it is unable to solve the power issue," Arvind Kejriwal alleged while addressing e-rickshaw drivers near Adarsh Nagar metro station here.
He said several areas in the city are facing power cuts and water shortage due to which people are angry with the Central government.
The Aam Aadmi Party chief reminded people of the power and water subsidies provided by his government in Delhi.
Kejriwal said his party is prepared to fight Assembly elections in Delhi and claimed that they would win by a big margin.
"They (BJP) keep saying there is a BJP wave in the city and country. If it is so, why are they not pushing for Assembly elections," he said.
"I challenge them to fight the elections again. We are sure we will come to power with a majority this time," he added.
Kejriwal said he regretted quitting the Delhi government, but said he did not "runaway" as alleged by his opponents.
"We did not runaway. Had we run away, we would have not returned. But now that we have come back, we are confident of wining and we will eradicate corruption from the system like we did earlier," Kejriwal said.
