Pakistan's army chief General Asim Munir will be promoted to the rank of field marshal, the prime minister's office said in a statement on Tuesday, the first time in almost 60 years that a general has been elevated to the role.

Pakistan’s prime minister has promoted the country’s powerful army chief, Gen. Asim Munir, to the rank of field marshal, making him only the second military officer in Pakistan’s history to hold the title.

Former Prime Minister Imran Khan, currently jailed, mocked the promotion of Pakistan's Army Chief Gen Asim Munir to Field Marshal by suggesting he be crowned "King" instead—claiming the nation is now ruled by "jungle law".
