JD(U), which had won 20 seats in the 2009 elections, was reduced to a mere two MPs this time while the former chief minister Lalu Prasad Yadav-led RJD won four seats. Congress bagged two seats and NCP had to be content with one.
Kumar had walked out of NDA and ended JD(U)'s 17-year-old relationship with BJP in June last year in protest against the elevation of Modi as BJP's prime ministerial candidate.
Jitan Ram Manjhi, who succeeded Kumar in the Bihar chief minister's chair, attended today's swearing in in Delhi.
While BJP is hoping to repeat its Lok Sabha showing in the Assembly elections next year, there are already indications of a realignment in the non-NDA camp there after Kumar's arch-rival in state politics, RJD, extended support to the Manjhi government in the trust vote.
Now, the good representation given to Bihar is likely to add teeth to the NDA's strength in Bihar.
