Two papers follow the Guardian's foremost talent (4)
I believe the answer is:
gift
'talent' is the definition.
(I know that talent can be written as gift)
'two papers follow the guardian's foremost' is the wordplay.
'two papers' can mean two replacements for 'paper'.
'paper' becomes 'I' (the i is a UK newspaper).
'paper' becomes 'FT' (newspaper the FT, Financial Times).
'follow' means one lot of letters go next to another.
'foremost' suggests taking the first letters.
The initial letter of 'guardians' is 'g'.
'i'+'ft'='ift'
'ift' after 'g' is 'GIFT'.
(Other definitions for gift that I've seen before include "Natural talent" , "A present or gratuity" , "Give away" , "Special aptitude - present" , "Present - natural aptitude" .)
