Prohibit nothing following check (4)

Ross

I believe the answer is:

veto

'prohibit' is the definition.
(synonyms)

'nothing following check' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'following' says to put letters next to each other.
'check' becomes 'vet' (I've seen this before).
'o' after 'vet' is 'VETO'.

(Other definitions for veto that I've seen before include "Overrule, forbid" , "bar" , "Disallow" , "An overriding negative vote" , "Reject - ban" .)

I've seen this clue in The Telegraph.
