Mukul Wasnik, General Secretary of Congress party announced candidates for Tarapur( Munger) and Kusheshvarasthan (Darbhanga) after unilaterally announcing candidates by RJD, sources say. The friction, sources say is seen after the participation of Tejaswi Yadav in the delegation led by CM of Bihar to represent their demand for the census on a caste basis. Congress GS said that party high command has approved the candidates for both the by-election. Sources say the Congress party wanted to contest from Kusheshvarasthan, a reserve constituency. RJD leadership claims that the announcement of their candidates is only after consultation with the leaders of the Congress party, sources say. Political observers say that unless these small issues are not tackled by the leadership of both the parties the continuance of Mahagathbandhan is likely to be in danger?
