Country ending in tremendous agony (5)

I believe the answer is:

spain

'country' is the definition.
(Spain is an example)

'ending in tremendous agony' is the wordplay.
'ending in' suggests the final letters.
'agony' becomes 'pain' (I've seen this before).
The last letter of 'tremendous' is 's'.
's'+'pain'='SPAIN'

(Other definitions for spain that I've seen before include "Country bordering Andorra" , "Take pains to go there" , "EU country" , "Catholic country" , "It pains one to be out in this country" .)

I've seen this clue in The Times.
