There was marginal improvement in the condition of veteran Marxist leader Jyoti Basu on Sunday, though he remained critical for the fifth successive day.

The medical board that is monitoring his condition described his state as “marginally better” and “still critical.” Mr. Basu continues to be on partial ventilation support in the Intensive Coronary Care Unit of a city hospital where he was admitted with pneumonia on January 1.

A bulletin issued by the hospital said his lungs were showing some signs of improvement with the infection being “adequately treated.”

On Saturday, the medical board found his condition to be deteriorating.

Mr. Basu’s cardiovascular system was more or less stable and his blood pressure was being maintained with a minimum dose of ionotropes (blood pressure stabilising drugs). The drowsiness Mr. Basu was suffering from on Saturday had lessened and “he moved his hands,” Dr. Sushrut Banerjee, one of the physicians attending on him, told journalist.
