Committee choosing team omitting top German princes (8)
I believe the answer is:
electors
'german princes' is the definition.
(elector was a historical type of German prince)
'committee choosing team omitting top' is the wordplay.
'committee choosing team' becomes 'selectors'.
'omitting top' means to remove the first letter.
'selectors' with its initial letter taken away is 'ELECTORS'.
(Other definitions for electors that I've seen before include "Those eligible to vote" , "They choose people for office" , "Voters" .)
