Why did Pakistan President Zardari get 'Mr 10%' tag, as mentioned in 'Dhurandhar 2'?

Pakistani President Asif Ali Zardari got the nickname 'Mr 10%' or '10% Zardari' in the 1990s. It originated from allegations that he used to demand 10% commission on government contracts, loans, and large-scale deals during his wife Benazir Bhutto's PM tenure. In 'Dhurandhar: The Revenge', Asif Ali Zarwari, character inspired by Zardari, was referred to as '10% Zarwari'.
