"He is not from a political background. He wants to serve the people of Punjab and hence he has decided to join AAP," Kejriwal added.Highlighting the freebies policies (electricity and water etc) and other developments being carried out by the Kejriwal government in Delhi for the last several years, AAP's convenor said the people of Punjab need change now."People of Punjab are fed up with both parties ruling here for the last 70 years and they want change now. They have taken the AAP as the best alternative in the state. I would appeal to the people of Punjab to support AAP in the next Assembly elections and you would find developments like Delhi. You have given multiple chances to the Congress, BJP and Shiromani Akali Dal but they did nothing except corruption. Give a chance to AAP and you will find a change in Punjab within five years," Kejriwal added.
