Why are the Brits covering up for Musharaff?

I ask again, why?

ISLAMABAD, Pakistan - Scotland Yard said in a report released Friday that Pakistan's opposition leader Benazir Bhutto died as a result of a suicide bomb blast, not a gunshot — findings that support the Pakistani government's version of the events.

They seem to be supporting the absurd theory that she died because she bumped her head. Most physicians have rejected that theory as highly improbable. So, why are the Brits joining in the cover-up? You can bet there's some back scratching going on somewhere.
