Bihar's ruling JD-U on Sunday urged all non-BJP parties, including the Congress, to accept the leadership of Chief Minister Nitish Kumar to challenge the party led by Prime Minister Narendra Modi.

Janata Dal-United state president Vashisht Narain Singh told media here that the time has come that all non-Bharatiya Janata Party (BJP) parties should come together at a platform and declare Nitish Kumar as their leader.

"In the changed situation in the country, Nitish Kumar is the only alternative to Modi," he said. Nitish Kumar is the president of JD-U.

Last year and this year as well, JD-U leaders and workers publicly tried to project Nitish Kumar as the prime ministerial candidate in the 2019 general election against Modi.
