The loos are plastic in this country (7)
I believe the answer is:
lesotho
'this country' is the definition.
(I know that Lesotho is a country)
'the loos are plastic' is the wordplay.
'are plastic' is an anagram indicator (plastic can mean easily moulded).
'the'+'loos'='theloos'
'theloos' anagrammed gives 'LESOTHO'.
'in' acts as a link.
(Other definitions for lesotho that I've seen before include "Independent kingdom, an enclave of South Africa" , "Country entirely within South Africa" , "South African kingdom" , "He loots (anag) -- southern African kingdom" , "Southern African country, capital Maseru" .)
