Trouble squashing publicity when bloomers become evident? (5)
I believe the answer is:
april
'when bloomers become evident?' is the definition.
(month when flowers bloom)
'trouble squashing publicity' is the wordplay.
'trouble' becomes 'ail' (synonyms).
'squashing' is an insertion indicator (I've seen this in other clues).
'publicity' becomes 'pr'.
'ail' going around 'pr' is 'APRIL'.
(Other definitions for april that I've seen before include "First of Herrick's four sweet months" , "whose first date is foolish?" , "Month that's autumnal in Oz" , "Month of showers and of the Queen's birthday" , "Eliot's 'cruellest month'" .)
