Potential titles for my radio play

• The Sub-Prime Minister
• The Un-Prime Minister
• The Prime Morrister
• Past his prime
• The Un-prime Example

I have chosen The Prime Morrister as a name. This is a good 'play on words' with the name of the central character. I can also use 'Prime Morrister' as a nickname that the public give him out of affection towards the end of the play.
