Bruce, for one, running wee errands (10)
I believe the answer is:
newsreader
'bruce' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?
'one running wee errands' is the wordplay.
'one running' indicates anagramming the letters (the letters run around to different places).
'wee'+'errands'='weeerrands'
'weeerrands' with letters rearranged gives 'NEWSREADER'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for newsreader that I've seen before include "Presenter of bulletin" , "TV employee" , "TV current affairs presenter" , "Bulletin broadcaster" .)
