Danger of liberal Irish record being overturned (5)
I believe the answer is:
peril
'danger' is the definition.
('peril' can be a synonym of 'danger')
'liberal irish record being overturned' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'irish' becomes 'ir' (abbreviation).
'record' becomes 'ep'.
'being overturned' is a reversal indicator.
'l'+'ir'+'ep'='lirep'
'lirep' written backwards gives 'PERIL'.
'of' acts as a link.
(Other definitions for peril that I've seen before include "risk" , "Danger of serious kind" , "Source of danger" , "Exposure to harm" , "Danger, jeopardy" .)
