Deletion of Chief of the Secret Intelligence Service

Comment: It is entirely reasonable to maintain an article about the leadership position of a nation's intelligence agency separate from one about the agency itself.  Compare this to the American Central Intelligence Agency/Director of the Central Intelligence Agency or the Soviet KGB/Chairman of the KGB.  The content and formatting of the article under discussion can likely be improved (and the tabular information removed from the parent article |accordingly), but none of that is cause for deletion
