Foolish reliance on Queen Elizabeth? (5,5)
I believe the answer is:
ocean liner
'queen elizabeth?' is the definition.
(RMS Queen Elizabeth is an example)
'foolish reliance on' is the wordplay.
'foolish' indicates anagramming the letters.
'reliance'+'on'='relianceon'
'relianceon' anagrammed gives 'OCEAN LINER'.
(Other definitions for ocean liner that I've seen before include "Cruise ship" , "Queen Mary, for example" , "Craft" .)
