Stepping up the campaign, a delegation of opposition leaders on Thursday met President Ram Nath Kovind and sought an immediate floor test in the Tamil Nadu assembly so that Chief Minister K. Palaniswami proves his legislative majority. Leaders from the DMK, Congress, Communist Party of India-Marxist (CPI-M) and Communist Party of India (CPI) told the President that the Palaniswami government had lost majority support as 19 MLAs owing allegiance to the Dinakaran faction in the AIADMK have told the Governor that they have withdrawn support to the Chief Minister.
