Former prime minister Nawaz Sharif is expected to return to the country on Friday.

Sharif had departed for London last Wednesday to spend time with his wife, Kulsoom Nawaz, who is undergoing treatment for lymphoma there. 

Sources said on Tuesday that Sharif will continue his 'public outreach campaign', launched following his disqualification by the Supreme Court, after his return to the country.

In this regard, sources said the Pakistan Muslim League-Nawaz (PML-N) supremo will address a public gathering in Abbottabad on September 10, followed by rallies in South Punjab as well as Karachi. 

Prior to his departure, Nawaz addressed a lawyers' convention in Lahore where he continued his tirade against his disqualification by the Supreme Court in the Panama Papers case.

Following the apex court's July 28 judgment, Nawaz stepped down as prime minister and, in a show of public support, led a rally from Islamabad to Lahore along the GT Road. 

As a result of Sharif's disqualification, his National Assembly seat, NA-120, was vacated. The PML-N has chosen Kulsoom as the party's candidate for the by-election, set to take place on September 17. 

In Kulsoom's absence owing to her medical treatment, Sharif's daughter Maryam is spearheading the electoral campaign in Lahore.
