One's relations are entertaining Eurocrat soused around noon? (9)
I believe the answer is:
raconteur
'one's relations are entertaining' is the definition.
(a raconteur relates stories)
'eurocrat soused around noon?' is the wordplay.
'soused' is an anagram indicator (a drunken or soused version of the letters).
'around' means one lot of letters goes inside another.
'eurocrat' anagrammed gives 'racoteur'.
'racoteur' going around 'n' is 'RACONTEUR'.
(Other definitions for raconteur that I've seen before include "He tells a good story" , "Skilful teller of tales" , "One can relate well" , "A good teller of tales" , "anecdotalist" .)
