Day off upheld in European Parliament? That’s a bloomer (8)
I believe the answer is:
daffodil
'a bloomer' is the definition.
(I've seen this before)
'day off upheld in european parliament?' is the wordplay.
'day' becomes 'd' (abbreviation for day).
'upheld' says the letters should be written in reverse.
'in' means one lot of letters goes inside another.
'european parliament?' becomes 'dail' (Dail Eireann, part of Irish parliament).
'd'+'off'='doff'
'doff' written backwards gives 'ffod'.
'ffod' going into 'dail' is 'DAFFODIL'.
'that's' is the link.
(Other definitions for daffodil that I've seen before include "Flower from bulb" , "National flower of Wales" , ""Welsh" flower?" , "Floral emblem of Wales" , "Type of 24 across" .)
