"Around six nurses are monitoring Thackeray's health round-the-clock," he said, adding, "the Sena chief is not keeping well".
Maharashtra Navnirman Sena chief Raj Thackeray, who visited his ailing uncle on Saturday, appealed to people to not believe in any rumours that are being spread about Bal Thackeray's health.
"There is no cause for worry. Bal Thackeray had asked me to come over to Matoshree," he had said.
Apart from Raj, former president Pratibha Patil also called on the senior Thackeray on Saturday along with her husband.
