Catch handlers going astray in the country (11)
I believe the answer is:
netherlands
'country' is the definition.
(Netherlands is an example)
'catch handlers going astray' is the wordplay.
'catch' becomes 'net' (netting is a kind of catching).
'going astray' indicates an anagram.
'handlers' with letters rearranged gives 'herlands'.
'net'+'herlands'='NETHERLANDS'
'in the' is the link.
(Other definitions for netherlands that I've seen before include "somewhere in Europe" , "European kingdom, capital Amsterdam" , "- Antilles includes island of Curacao" , "North European country" , "Their government at The Hague" .)
