Digger wants flat in Seascale vacated (5)
I believe the answer is:
spade
'digger' is the definition.
(I've seen this before)
'flat in seascale vacated' is the wordplay.
'flat' becomes 'pad' (a person's home).
'in' indicates putting letters inside.
'vacated' says to hollow out the word (remove centre letters) (internal letters vacate the word).
'seascale' with its centre removed is 'se'.
'pad' placed within 'se' is 'SPADE'.
'wants' acts as a link.
(Other definitions for spade that I've seen before include "Small shovel" , "Fictional detective" , "Shovel-like tool" , "a gardener's needs?" , "that has a cutting edge" .)
