'Credible evidence' MI6 spy died alone, says pathologist
A pathologist who carried out a post mortem examination on the MI6 officer Gareth Williams has said the possibility he died alone should be re-examined.
The body of the 31-year-old from Anglesey was found inside a locked bag. A coroner said it was unlikely he got into it by himself.
But there are new claims, he could have done so.
