Being singular right winger reveals full personal details (4,5)
I believe the answer is:
life story
'winger reveals full personal details' is the definition.
I can't judge whether this definition defines the answer.
'being singular right' is the wordplay.
'being' becomes 'life' (life is a kind of being).
'singular' becomes 's' (abbreviation sometimes used in dictionaries).
'right' becomes 'tory' (Tory can mean Conservative or right-wing).
'life'+'s'+'tory'='LIFE-STORY'
Can you help me to learn more?
(Other definitions for life story that I've seen before include "Autobiography" , "Biography" .)
