Lucknow, Jan 29 : Bihar Chief Minister Nitish Kumar snapping ties with INDIA bloc and again joining NDA has come as a jolt to alliance partners in Uttar Pradesh between Samajwadi Party (SP) and Congress.

Both parties feel that the developments in Bihar have undermined their position in UP against the BJP.

Nitish Kumar not only laid the foundation of the INDIA bloc, but had also worked to unite the opposition on a single platform by meeting with leaders of different political parties and convincing them to join hands against the BJP.
