Spring tax returns for Picasso? (8)
I believe the answer is:
spaniard
'picasso?' is the definition.
(Picasso is from spain)
'spring tax returns' is the wordplay.
'spring' becomes 'spa' (I've seen this before).
'tax' becomes 'drain'.
'returns' is a reversal indicator.
'drain' reversed gives 'niard'.
'spa'+'niard'='SPANIARD'
'for' acts as a link.
(Other definitions for spaniard that I've seen before include "Slope-measuring instrument" , "Type mostly found in Madrid" , "European national" , "Malaga man or woman, perhaps?" , "A native of Iberian country" .)
