What can stop British playboy duke entering insane plea? (5,5)
I believe the answer is:
brake pedal
'what can stop' is the definition.
I can't tell whether this defines the answer.
'british playboy duke entering insane plea?' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'playboy' becomes 'rake' (old-fashioned term for a womanising man).
'duke' becomes 'd' (abbreviation).
'entering' indicates putting letters inside.
'insane plea?' becomes 'peal' (I can't explain this - if you can you should believe this answer much more).
'd' going within 'peal' is 'pedal'.
'b'+'rake'+'pedal'='BRAKE PEDAL'
Can you help me to learn more?
