Kanti Singh along with seventeen Loksabha MPs and eight Rajyasabha MPs besides thousands of supporters and activists assembled at, New Delhi and took the historic decision to form a new Political Party under the name "Rashtriya Janata Dal- RJD". Shri Lalu Prasad was elected as the President of "Rashtriya Janata Dal- RJD".
