Former military ruler Pervez Musharraf will appeal in the country's highest court on Thursday against an order for his arrest, a party spokesman said.

The spokesman for Musharraf's All Pakistan Muslim League told AFP that if the order is upheld, then he expected the authorities to put the retired general under house arrest at his property on the edge of Islamabad.

"Musharraf is composed and confident. We will go for an appeal in the Supreme Court today. If the court rejects our appeal, we will present ourselves to the law," APML spokesman Muhammad Amjad said.

"I think if an arrest is necessary, the authorities will declare the farm house a sub-jail," he added.
