Various political parties have started a protest expressing dissatisfaction over the naming of Province 1. Normal life in Sunsari, Morang and Jhapa districts has been affected due a bandh enforced by the Janata Samajbadi Party and Federal Limbuwan Party among others. Markets and shops pulled down their shutters from early morning in the districts while vehicles stayed off the roads.

Janata Samajbadi Party central member Bhim Rai said that they were forced to enforce the bandh after their identity movement was ignored by naming Province 1 as Koshi Province forcefully.

Janata Samajbadi Party another leader Sagar Chemjong has warned of stern protests if their demands are not addressed. The parties have mobilized hundreds of cadres on the streets to make bandh successful. Province 1 officially adopted Koshi as its new name on March 1.
