Pakistani former military ruler Pervez Musharraf is due to go on trial on treason charges, BBC News reported.

He will appear before a special court in Islamabad - a day after his petition that only a military court could examine his actions was rejected.

The charge relates to his decision in 2007 to suspend the constitution and impose emergency rule.

Musharraf, who is on bail in several other cases, says all the accusations against him are politically motivated.

The 70-year-old also faces separate charges of murder and restricting the judiciary. He is the first Pakistani former military ruler to face trial for treason.
