Slight improvement in ex-Bengal CM Buddhadeb Bhattacharya’s health condition

The health condition of former West Bengal chief minister Buddhadeb Bhattacharya improved slightly though he remained critical on Sunday morning, doctors treating him at a city-based hospital, said. The oxygen saturation of the 79-year-old Bhattacharya, who was rushed to the private hospital from his Palm Avenue residence via a green corridor on Saturday afternoon, improved slightly, but he continued to be on invasive ventilation, a senior doctor said.
