The Congress on Monday indicated it may be joining the Nitish Kumar government in Bihar, after the decisive victory of the Grand Alliance in the assembly polls.Asked whether the Congress was open to the idea of joining the Bihar government, party spokesperson C.P. Joshi said: "When we say we have given commitment to the people of Bihar, then it is our responsibility to implement the seven-point programme. Then we will naturally consider all these aspects. We owe it to the people of Bihar."On entering into similar alliance with other parties in other states, he said: "It will depend on the political challenges and organisational strength of the party in those states."The Grand Alliance of the Janata Dal-United (JD-U), Rashtriya Janata Dal (RJD) and the Congress won a whopping 178 of the 243 Bihar assembly seats, leaving the BJP and its allies with just 58 seats.
