The much-awaited rath yatra of BJP is finally flagged off from Nabadwip, West Bengal amidst uncertainty over the nod from the concerned authorities. Ahead of crucial assembly polls in West Bengal, BJP national chief JP Nadda on Saturday flagged off the party's 'Poribortan Yatra' (March for Change) in the state. During the ceremony, Nadda said he feels "enthused" by the yatra and it is time for a change in Bengal. "'Poribortan Yatra' begins here. It is a change of not only the government but also of thinking," JP Nadda said while flagging off the yatra in Nabadwip.
