Kept in readiness in old Mediterranean resort (2,3)
I believe the answer is:
on ice
'kept in readiness' is the definition.
(I've seen this before)
'old mediterranean resort' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'mediterranean resort' becomes 'nice' (I've seen this in another clue).
'o'+'nice'='ON ICE'
'in' acts as a link.
(Other definitions for on ice that I've seen before include "In abeyance" , "Awaiting decision" , "Temporarily suspended" , "Waiting" , "Where one might find slippers" .)
