Expelled Congress leader Barkha Shukla Singh today joined the Bharatiya Janata Party.
Singh was expelled from the Congress on Friday for undertaking anti-party activities.
On Thursday she resigned from all party posts raising questions over the leadership of Vice President Rahul Gandhi and Delhi unit chief Ajay Maken.
While resigning as chief of DPCC's women wing, Barkha Singh had said: "Rahul Gandhi is unfit to lead the party."
