The Pakistan Tehrik-e-Insaf (PTI) will begin the long march towards Islamabad against the sitting corrupt rulers and foreign conspiracy in the last week of May, former prime minister Imran Khan announced on Saturday.

"We will be giving this call to all Pakistanis, not just PTI supporters, as Pakistan has been insulted after the country's most corrupt people were imposed on us by a foreign power," Imran said in a video statement.

Imran said most corrupt people have been imposed on the country under the foreign conspiracy, adding that 60 per cent of the cabinet members of Shahbaz Sharif are also on bail.
"Shahbaz Sharif is dubbed as the crime minister,” he said and added his (family) has corruption cases worth Rs40 billion pending in the FIA and NAB.

The PTI chairman reiterated that such people being in power was an "insult" to Pakistan.

Imran was ousted from power on April 10 after the National Assembly voted against him on the no-confidence motion — making him the first premier to be voted out through the move.

Imran had repeatedly blamed the US for backing the no-confidence motion and has refused to accept newly elected PM Shahbaz, saying "there can't be any bigger insult to this country." The Joe Biden-led administration in the US, however, has denied the allegations.

In his video message released on Saturday, the ex-prime minister said the preparations for the long march would begin on the eve of Eid Al Fitr and urged the youth to come out on the streets with PTI's flags in their hands.

"You will have to tell the world that Pakistan is a nation that is alive [...] and once the preparations begin, our next target will be Islamabad," the PTI chairman said.

Former premier said he believed that a sea of people will storm Islamabad and give a clear message to the people: "From now on, no one from abroad can impose a corrupt government on us. Pakistani people will decide Pakistan's fate."
