Say that members of the media are pursuing former partner (7)
I believe the answer is:
express
'say that members' is the definition.
'express' can be an answer for 'say' (to express something is to say it). I am unsure of the rest of the definition.
'media are pursuing former partner' is the wordplay.
'media' becomes 'press' (the press is part of the media).
'are pursuing' means one lot of letters go next to another.
'former partner' becomes 'ex' (an ex-partner).
'press' after 'ex' is 'EXPRESS'.
'of the' acts as a link.
Can you help me to learn more?
(Other definitions for express that I've seen before include "Fast - state - train" , "for a specific purpose?" , "Say; fast train" , "Quick -- exact" , "Convey; particular; train" .)
