Lady journalists covering extreme parts of empire (7)
I believe the answer is:
peeress
'lady' is the definition.
(female peer)
'journalists covering extreme parts of empire' is the wordplay.
'journalists' becomes 'press' (the press can mean the newspaper industry).
'covering' is an insertion indicator.
'extreme parts of' says to hollow out the word (remove centre letters) (the letters on the extremes of the word are used).
'empire' with its centre removed is 'ee'.
'press' going around 'ee' is 'PEERESS'.
(Other definitions for peeress that I've seen before include "Female noble" , "She is married to a duke, earl etc" , "Lady" , "Female House of Lords member" , "Woman from other place" .)
