'glamorous mp said the parrot' is the definition.
I can't judge whether this definition defines the answer.

'said the parrot' is the wordplay.
'said' becomes 'pretty' (I can't explain this - if you can you should give a lot more credence to this answer).
'the parrot' becomes 'polly' (I've seen this before).
'pretty'+'polly'='PRETTY POLLY'

Can you help me to learn more?
