Top class deal arranged and maintained by country’s foremost soldiers, repeatedly (5,2,2,5)
I believe the answer is:
creme de la creme
'repeatedly' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'top class deal arranged and maintained by country's foremost soldiers' is the wordplay.
I cannot quite understand how this works, but
'class' could be 're' (Religious Education, school subject) and 're' is located in the answer.
an anagram of 'deal' is 'dela' which is within the answer.
'soldiers' could be 'reme' (Royal Electrical and Mechanical Engineers) and 'reme' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for creme de la creme that I've seen is " (The) very best".)
