Amarinder Singh undergoes spinal surgery in London

Former Punjab chief minister Amarinder Singh underwent a successful spinal surgery in a London hospital on Saturday.

A statement quoting 80-year-old Singh's MP wife Preneet Kaur, who is with him in London, said the surgery was successful and he was shifted to a private room in the hospital.

He will be discharged on Monday, she said in a tweet later.

"We are thankful to all of you for your prayers & good wishes," she said.

Singh had gone to London recently. The former chief minister heads the Punjab Lok Congress outfit, which is an ally of the BJP.
