Kalyan Singh, the former Chief Minister of Uttar Pradesh on 21 January 2013 merged his Jan Kranti Party with Bhartiya Janta Party. Singh merged his party with BJP during the Atal Shankhnaad Rally of BJP in Lucknow’s Jhelum Park.
He himself was unable to join the party himself as he is an independent MP from Etah Constituency and before joining the party it is required for him to resign from the membership of the house as it is an electoral cause under anti-defection law.
