Before leaving for Delhi, Kejriwal thanked doctors of the hospital where he underwent the surgery.

"Discharged today after surgery. Thank u so much Kiranji, Dr Shetty n Dr Paul. Can't express my gratitude in words (sic)," Kejriwal tweeted.

BJP and Congress have criticised Kejriwal and his deputy Manish Sisodia for "being away" from the national capital at a time when Delhi is grappling with the outbreak of dengue and chikungunya.

Sisodia is also scheduled to return today to Delhi from Finland where he had gone to understand its education system. Earlier this week, Congress had observed 'Bhagoda Diwas', saying Kejriwal and half of his cabinet were "absent" from Delhi.

"He is doing well, there is no problem. He is able to talk, but we are restricting him," officials at the Narayana Health City had said after the surgery.
