New Delhi, August 12: The health condition of former Lok Sabha speaker Somnath Chatterjee deteriorated on Sunday morning following which he has been put on a ventilator support. The CPI(M) veteran has been suffering from various diseases.

Earlier in June, Chatterjee had suffered a hemorrhagic stroke after which his health declined. He had also suffered a mild cerebral stroke back in 2014.

The family members and doctors attending him did not disclose the ailment due to which the 89-year-old former parliamentarian was admitted to the ICU earlier this week. The family members do not want the ailment to be disclosed, the official had said.

Chatterjee, a former CPI(M) leader and 10-time Lok Sabha MP, was speaker of the Lok Sabha in the first Congress-led UPA government from 2004-2009.

The CPI(M) expelled him in 2008 for not resigning as the speaker after the party withdrew its support from the UPA-1 government over Indo-US nuclear deal.
