One following an EU president, holding a type of pasta (8)
I believe the answer is:
macaroni
'type of pasta' is the definition.
(I've seen this before)
'one following an eu president holding a' is the wordplay.
'one following' is a charade indicator (letters next to each other).
'an' becomes 'i' (Roman numeral for one).
'eu president' becomes 'Macron' (Emmanuel Macron, president of France).
'holding' means one lot of letters goes inside another.
'macron' enclosing 'a' is 'macaron'.
'i' after 'macaron' is 'MACARONI'.
(Other definitions for macaroni that I've seen before include "Short narrow tubes of pasta" , "2 [PASTA]" , "Short thick tubes of pasta (8)" , "Pasta for Marciano" , "With which one tube-feeds" .)
