The move comes at a time when AAP leaders, including Delhi Chief Minister Arvind Kejriwal, have accused the BJP of indulging in horse trading. Bajpai joined the BJP in the presence of party national vice-president and Delhi BJP in-charge Shyam Jaju and Union minister Vijay Goel at the Delhi unit office here.

"I worked with the AAP for many years. I was hurt by the lack of respect and the peculiar functioning of the party. It has detracted from its original path," he said. Reacting to the development, senior AAP leader Gopal Rai said that his party has for sometime been accusing the BJP of trying to "buy" its MLAs.
