Somnath Chatterjee suffered a hemorrhagic stroke in June and was hospitalised for more than a month.

The condition of former Lok Sabha Speaker Somnath Chatterjee (89) continued to be critical on Sunday after he suffered from a mild heart attack. Mr. Chatterjee has been on ventilation for the last five days after he was admitted to a private hospital in Kolkata on Tuesday due to kidney related complications.

“Mr. Chatterjee suffered a mild heart heat attack today (Sunday) but has recovered from it,” said a senior official of the Belle Vue Clinic where Mr. Chatterjee is admitted. Hospital authorities also said that Mr. Chatterjee had to undergo dialysis on a daily basis as his kidneys are not functioning properly.

“He continues to be in critical but stable condition. But anything can happen when an 89 year old man is suffering from total kidney shut down and is on dialysis. We are trying our best,” Pradeep Tandon, CEO of Belle Vue clinic, told The Hindu.

He suffered a hemorrhagic stroke in June and was hospitalised for more than a month.

Mr. Chatterjee was the Speaker in the first five-year term (2004-2009) of the United Progressive Alliance government and was elected to the Parliament's Lower House for ten times since 1971.

He was expelled from the Communist Party of India-Marxist (CPI-M) in July 2008 for refusing to resign as Speaker after CPI-M withdrew support from the United Progressive Alliance (UPA) government.
