Can let room rebuilt in Mediterranean resort (5,5)
I believe the answer is:
monte carlo
'mediterranean resort' is the definition.
(I've seen this before)
'can let room rebuilt' is the wordplay.
'rebuilt' indicates an anagram.
'can'+'let'+'room'='canletroom'
'canletroom' with letters rearranged gives 'MONTE CARLO'.
'in' acts as a link.
(Other definitions for monte carlo that I've seen before include "Swanky part of France" , "Town near Nice" , "Gamblers' resort" , "place of speculation" , "Riviera resort" .)
