She's one point in the lead, for a change (5)
I believe the answer is:
adele
'she's' is the definition.
'one point in the lead for a change' is the wordplay.
'one point' becomes 'e' (compass point).
'in' is an insertion indicator.
'for a change' is an anagram indicator.
'lead' is an anagram of 'adle'.
'e' placed within 'adle' is 'ADELE'.
(Other definitions for adele that I've seen before include "Performer" , "Female singer from London" , "Woman" , "Singer with albums titled 19, 21 and 25" , "girl" .)
