Outstanding leader of Denmark uplifting continental bloc (3)
I believe the answer is:
due
'outstanding' is the definition.
(an outstanding debt is due)
'leader of denmark uplifting continental bloc' is the wordplay.
'leader of' says to take the initial letters.
'uplifting' says the letters should be written in reverse.
'continental bloc' becomes 'eu' (I can't explain this - if you can you should give a lot more credence to this answer).
The first letter of 'denmark' is 'd'.
'eu' back-to-front is 'ue'.
'd'+'ue'='DUE'
Can you help me to learn more?
(Other definitions for due that I've seen before include "Owing, unpaid" , "Entitlement" , "Owed, or payable immediately" , "Payable; deserved" , "...more than one there [ROME]" .)
