Imports business reduced by half reorganised in one-sided arrangement (6,5)
I believe the answer is:
mobius strip
'one-sided arrangement' is the definition.
The definition suggests a singular noun which matches the answer.
'imports business reduced by half reorganised' is the wordplay.
'reduced by half' indicates taking half.
'reorganised' indicates an anagram.
'business' halved is 'busi'.
'imports'+'busi'='importsbusi'
'importsbusi' anagrammed gives 'MOBIUS STRIP'.
'in' is the link.
Can you help me to learn more?
(Another definition for mobius strip that I've seen is " Surface with one continuous side, formed by joining the ends of a rectangle after twisting it - I stir up mobs (anag)".)
