Daughter in Mile End disrupted grand district for conservative constituency? (6,7)

I believe the answer is:
middle england
'daughter in mile end disrupted grand' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'district for conservative constituency?' is the wordplay.
I cannot really understand how this works, but
'district' could be 'england' (England is an example) and 'england' is present in the answer.
The remaining letters 'middle' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for middle england that I've seen before include "Conservative section of society" , "Suburbia" .)
