Do foes struggle to secure end of Nicola Sturgeon, perhaps? (7)
I believe the answer is:
seafood
'sturgeon perhaps?' is the definition.
'do foes struggle to secure end of nicola' is the wordplay.
'struggle' indicates an anagram (I've seen 'struggling' mean this).
'to secure' means one lot of letters goes inside another (inserted letters are secured inside).
'end of' suggests the final letters.
The final letter of 'nicola' is 'a'.
'do'+'foes'='dofoes'
'dofoes' with letters rearranged gives 'sefood'.
'sefood' placed around 'a' is 'SEAFOOD'.
(Other definitions for seafood that I've seen before include "Such as prawns, tuna" , "Eaten fish and shellfish" , "Shellfish, marine fish" , "Edible fish, shellfish etc from the oceans" , "The "surf" of a surf 'n' turf dish" .)
