Plants piece of information with politicians using timeshare arrangement (9)
I believe the answer is:
factories
'plants piece of information' is the definition.
'factories' can be an answer for 'plants' (I've seen this in another clue). I'm not certain of the 'piece of information' bit.
'politicians using timeshare arrangement' is the wordplay.
I cannot quite see how this works, but
'politicians' could be 'tories' (informal term for the Conservative Party) and 'tories' is located in the answer.
This explanation may well be incorrect...
'with' acts as a link.
Can you help me to learn more?
(Other definitions for factories that I've seen before include "Manafacturing plants" , "Manufacturing plants" .)
