A UN commission of inquiry is set to present the findings of its investigation into the assassination of Benazir Bhutto, the former Pakistani prime minister.

Bhutto, who was the first woman to become the prime minister of a Muslim country, was killed in a gun and suicide bomb attack on December 27, 2007, after addressing an election rally in the Pakistani city of Rawalpindi, near Islamabad, the capital.

The UN planned to publish the report two weeks ago, but delayed it following a request by Pakistan to allow for investigation contributions from other countries.

However, with much of the key evidence missing the findings may not bring clarity and will most likely not bring agreement.
