Soon get a French veto (4)

Here is my best explanation:

'soon' is the definition.
(I've seen this before)

'get a french veto' is the wordplay.
'get' says to put letters next to each other.
'french veto' becomes 'non' (French for 'no', a word which might veto something).
'a' next to 'non' is 'ANON'.
