Addressing enthusiastic supporters at the Ramlila Maidan here, Kejriwal said: "The decision to fight polls across the country after winning 28 seats in the last assembly polls was a result of our arrogance. And we could see the results."
The chief minister said he could see a little arrogance in some leaders when they said on television that "we will fight polls in other states".
"This is not right. Why did Congress lose, they had become arrogant. The BJP which got such a massive mandate in Lok Sabha polls in May, but this time (assembly elections) it lost due to arrogance," he said.
"I have decided and God has told me, I will only be in Delhi for the next five years and fulfill my responsibility," Kejriwal added.
