Former Lok Sabha Speaker Somnath Chatterjee has been put on ventilator support and dialysis after his health situation became critical, ANI reported on Sunday. He was admitted to a hospital in Kolkata on Friday with kidney ailments.

In June, the 89-year-old was admitted to the critical care unit of a private hospital in Kolkata with a brain clot. He was also suffering from ailments in his lungs, liver and urinary tract. In 2014, Chatterjee had suffered a mild cerebral stroke, reported The Indian Express.

Chatterjee, a former veteran of the Communist Party of India (Marxist), is a 10-time Lok Sabha MP. He was the Speaker of the Lower House from 2004 to 2009. In 2008, he was expelled from the Communist Party of India (Marxist) for not resigning as the Speaker after the party withdrew support from the United Progressive Alliance government over the Indo-US nuclear deal.
