Dravida Munnetra Kazhagam Rajya Sabha member Kanimozhi on Wednesday submitted her resignation from the Upper House to party chief and her father M Karunanidhi in line with the decision of an all-party meeting to put pressure on the Centre to call for a ceasefire in Sri Lanka.
Her resignation comes a day after the all-party meeting on the issue of Sri Lankan Tamils passed its resolution that all members of Parliament from Tamil Nadu would quit within a fortnight to press the demand.
Kanimozhi told PTI that it was for the party to take an "appropriate decision at appropriate time" on her resignation.
She said Tuesday's resolution had given two weeks' time to the Centre to take steps to pressurise Sri Lanka for a ceasefire in the Tamil-speaking northern part, where the island army is on a final push against the Liberation Tigers of Tamil Eelam.
Highly placed DMK sources said that as the resolution was applicable to Rajya Sabha members also, Kanimozhi handed over her resignation to Karunanidhi.
While the meeting was attended by the DMK, the Congress, the Left and a few other parties, the principal opposition All India Anna Dravida Munnetra Kazhagam with its ally Marumalarchi Dravida Munnetra Kazhagam, the Bharatiya Janata Party and the Desiya Murpokku Dravida Kazhagam boycotted it, describing the initiative as an "eye-wash".
