Islamabad: Pakistan Tehreek-e-Insaf (PTI) leader Imran Khan has offered to call off the sit-in of his party near parliament here on the condition that Prime Minister Nawaz Sharif declare all his personal and family assets inside and outside the country.

Khan, while addressing his party workers and supporters overnight, said he had already made public details of his assets all of which were in Pakistan.

He said if anyone proves concealment or tax evasion on his part he would say goodbye to politics for ever.

Accusing Sharif family of building wealth through corrupt means, the PTI leader challenged the prime minister to come clean on his assets.

The PTI chairman, who has vowed to continue the sit-in until Sharif steps down, asked his supporters to turn up in large numbers for obseriving a “Go Nawaz Go” day.

Pakistan Awami Tehreek (PAT) leader Tahirul Qadri has also regularly lashed out at the ruling family in his routine daily addresses to the participants of the party’s sit-in beside that of the PTI.

Information Minister Pervaiz Rasheed has hit back at the two protesting politicians, blaming them for dishing out pure lies in their routine harangues without any evidence in support of their allegations.

The minister has said the government was in the process of collecting evidence against the PTI and PAT leaders to submit the same in courts, including video footages of their speeches. “We will unmask them in courts.”

In his address at the sit-in on Wednesday, Tahirul Qadri referred to a First Information Report (FIR) or complaint reportedly registered by police in Islamabad against the prime minister and others, including ministers, and said Sharif should immediately quit.

According to media reports, the capital police registered the FIR late Tuesday night under an order issued by a district and sessions court.

On Monday the court had asked the Secretariat police to register an FIR while disposing of a petition by PAT over the alleged killing of its three workers in Islamabad on August 30 during police action.

Both PTI and PAT stalled talks with the government last week in protest against the alleged large scale arrests of their workers, dealing a blow to the quest for a peaceful resolution of the political crisis.

While the parliament was due to resume a joint session of its two houses on Wednesday evening after a break of several days, chief of Jamaat-e-Isami party Sirajul Haq announced he, along with other politicians, would strive to bring the two sides back to the negotiating table.
