Puducherry Chief Minister V Narayanasamy and his cabinet colleagues besides ruling side MLAs in the union territory resigned on Monday after the government lost the confidence vote sought by him in the face of its depleted strength of 11 against the opposition's 14 in the House. After staging a walkout from the Assembly before the motion seeking confidence vote was put up for voting in the House, Narayanasamy proceeded to the Raj Nivas and submitted his resignation to Lt Governor Tamilisai Soundararajan.
