Good! One newspaper has flair (4)
I believe the answer is:
gift
'flair' is the definition.
(I've seen this in another clue)
'good one newspaper' is the wordplay.
'good' becomes 'g' (abbreviation).
'one' becomes 'i' (Roman numeral).
'newspaper' becomes 'FT' (Financial Times newspaper).
'g'+'i'+'ft'='GIFT'
'has' is the link.
(Other definitions for gift that I've seen before include "''Never look a .... horse in the mouth" , "A present or gratuity" , "Give away" , "Natural talent" , "Donation" .)
