The audio message of the former PM has been shared on his daughter Maryam's Twitter handle.

Maryam, who is a prominent political face in Pakistan, is also currently lodged in jail.

In his audio message, Sharif said: "I, Mohammad Nawaz Sharif, is speaking from the prison and the historic day of July 25 is just around the corner."

"Set out of your homes after the Fajr prayers on July 25, with utmost resolve and determination, and vote for Muslim League-Nawaz for your dignity and sanctity of your vote," he said.

In a major blow to Nawaz Sharif ahead of the general elections, a Pakistani court on July 6 handed over the former Prime Minister, his daughter and son-in-law jail terms, over his family’s purchase of upscale London flats. 

Sharif was awarded ten years in jail and fined eight million pounds by the Pakistani court, while his daughter Maryam was sentenced to eight years in jail and fined two million pounds by the court.

They were arrested on July 13 after they reached Pakistan from London.

They are currently lodged in Adiala jail in Pakistan.
