Members of the United Nations (UN) inquiry commission probing the “facts and circumstances” of the Benazir Bhutto assassination case are expected to quiz Pakistan’s former president Pervez Musharraf in London.

The three-member commission, which formally started its work on July 1, 2009, has already held meetings with a range of Pakistani citizens, political leaders and government officials, Michele Montas, spokesperson for UN secretary-general Ban ki-Moon, told reporters in New York. In July, the members had visited Rawalpindi where the former prime minister was killed.

Pakistan had sought the UN probe after its own investigations and one by Scotland Yard failed to make any headway. Musharraf was the president when the assassination took place.

Baitullah Mehsud, former chief of the Tehreek-e-Taliban Pakistan, who was killed in a US drone strike in early August, was one of the key suspects.
