The chief minister said his government was determined to take stringent action against anyone corrupt whether in the previous Congress government, MCDs controlled by the BJP and or anybody in his government.
In his nearly 20-minute long speech, Kejriwal emphasised that he would continue his fight against corruption vigorously as AAP was formed to uproot corruption from politics.
"We are not here to save this government. We had formed the party to cleanse politics of the country. Today, the politics is entrenched in graft. Two years ago, we demanded that the system should be freed from corruption. Then politicians ridiculed us. They challenged us to contest elections. We took the challenge and on December 4, a miracle had taken place.
