Ecstatic journalist coming round at the last minute? (6)
I believe the answer is:
elated
'ecstatic' is the definition.
(I've seen this before)
'journalist coming round at the last minute?' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'coming round' indicates putting letters inside.
'at the last minute?' becomes 'late' (I've seen this in other clues).
'ed' placed around 'late' is 'ELATED'.
(Other definitions for elated that I've seen before include "Exultant" , "In very high spirits, really chuffed" , "Filled with joy and pride" , "Feeling overjoyed and happy" , "Highly delighted" .)
