Was Edward not utilised? (6)
I believe the answer is:
wasted
'utilised?' is the definition.
(wasting is a kind of utilising)
'was edward' is the wordplay.
'edward' becomes 'ted'.
'was'+'ted'='WASTED'
'not' acts as a link.
(Other definitions for wasted that I've seen before include "Drunk (as a missed opportunity?)" , "Squandered or weakened" , "Squandered, dissipated" , "Used unprofitably or lost weight" , "Not used to good advantage" .)
