Islands involving revolutionary in trade agreement reflecting (10)
I believe the answer is:
seychelles
'islands' is the definition.
(island nation)
'revolutionary in trade agreement reflecting' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'in' indicates putting letters inside.
'trade' becomes 'sell' (to sell is to trade something for money).
'agreement' becomes 'yes' (saying yes to something).
'reflecting' says the letters should be written in reverse.
'sell'+'yes'='sellyes'
'sellyes' backwards is 'seylles'.
'che' placed inside 'seylles' is 'SEYCHELLES'.
'involving' is the link.
(Other definitions for seychelles that I've seen before include "Indian-Ocean islands" , "Island country" , "Island group in the western Indian Ocean" , "Indian Ocean islands" , "Group of islands" .)
