Pakistan's jailed former Prime Minister Imran Khan, who blames the military for his ouster and 12-month-old imprisonment on what he calls trumped-up charges, said on Sunday it would be "foolish" not to have "excellent" relations with the army.

Ahead of Monday's anniversary of his jailing on dozens of charges ranging from corruption to leaking state secrets, Khan also said in written responses to questions that he held no grudges against the United States, whom he has also blamed for his 2022 ouster from office.

"Given Pakistan's geographical position and the military's significant role in the private sector, it would be foolish not to foster such a relationship," Khan wrote in replies relayed by his media and legal team.
