Nawaz Sharif sons Hassan and Hussain Nawaz were insulted by people who saw them walking in the streets of London.
The man made video calling them corrupt thieves who looted the resources of Pakistan. The man asked from which money you purchased flats in London, and through which bank the amount was transferred.
The man continuously asked them to show receipts if they are not liars. But they silently walked giving no answer to the man.
