Pakistan's prime minister will undergo open heart surgery next week.
Nawaz Sharif will have his second cardiac operation in five years in London Tuesday.
The prime minister's daughter, Maryam Nawaz Sharif, has written about the upcoming operation on her Twitter account.
She said the surgery would be for "perforation of the heart," and is a complication from a previous operation in 2011.
The prime minister's daughter said her father would have a week-long recovery period and that "prayers are needed."
A statement from the prime minister's office Saturday said it is "natural and understandable" that Sharif "will be off from any activities when he is actually operated on by the doctors."
India's prime minister, Narendra Modi, wished Sharif a speedy recovery in a tweet.
