Based on the provided information, the straightforward answer is no one.
According to the reference from the List of prime ministers of Pakistan on Wikipedia, no prime minister of Pakistan has yet served their full five-year term.
This is a notable fact in Pakistan's political history, where terms for Prime Ministers have often been cut short due to various reasons, including:
- Dismissals
- Military coups
- Dissolution of assemblies
- Resignations
While some Prime Ministers have served significant periods, none have completed the constitutionally mandated five-year term in office.
Here is a simple list reinforcing this point:
- Key Fact: No Prime Minister in Pakistan's history has successfully completed a full five-year tenure.
- Source: List of prime ministers of Pakistan - Wikipedia
This consistent inability for a Prime Minister to serve a full term highlights a historical pattern of political instability in Pakistan.
