According to media reports, Imran Khan and Chaudhry Nisar met accidentally at a restaurant where the two had arrived for dinner.
In the meantime, reports added, both had a prolonged ‘gossip’.
Nisar, one of the closest aides of the premier, had lashed out his grievances in a candid press conference ahead of Panama verdict.
The minister said he had clashed with members of Sharif’s Pakistan Muslim League-Nawaz (PML-N) over how to tackle the Panama Papers leak, which led to an investigation into how Sharif obtained his wealth.
He said his heart was no longer in politics and he wanted to end his 33-year association with PML-N. “I’m done with politics,” he added.
