Raised tax in east Leeds endlessly (8)
I believe the answer is:
elevated
'raised' is the definition.
('elevate' can be a synonym of 'raise')
'tax in east leeds endlessly' is the wordplay.
'tax' becomes 'vat' (British sales tax).
'in' indicates putting letters inside.
'east' becomes 'e' ('E' can be a synonym of 'east').
'endlessly' means to remove the last letter.
'e'+'leeds'='eleeds'
'eleeds' with its final letter taken off is 'eleed'.
'vat' going within 'eleed' is 'ELEVATED'.
(Other definitions for elevated that I've seen before include "exhilarated" , "Raised up as to peerage" , "Exalted; lifted" , "Lofty" , "by such an American railway?" .)
