Pakistan Prime Minister Nawaz Sharif will undergo open-heart surgery in London on Tuesday, his second major cardiac medical procedure in five years.
He is expected to stay in hospital for around a week after the procedure to recover before travelling home.
The details of his illness were not given, but in a series of tweets, Maryam Nawaz Sharif said her father had been experiencing unspecified symptoms.
A statement issued by his office in Islamabad said: “In London, the Prime Minister is overseeing the affairs of the state as he is duly assisted by his principal secretary, military secretary and other staff members.”
“The Prime Minister is kept abreast on routine matters of the country and his directions are accordingly conveyed to the concerned quarters,” the statement said.
Mr Sharif has been under pressure since the so-called Panama Papers leak linked his family to a series of offshore companies. On Monday, the PM presided over meetings of the cabinet and National Economic Council via a video link to clear way for the national budget to be presented on June 3.
