Junk energy emitted by toothless prime minister (4)
I believe the answer is:
eden
'prime minister' is the definition.
(Anthony Eden, UK PM 1955-57)
'junk energy emitted by toothless' is the wordplay.
I cannot really see how this works, but
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is located in the answer.
The remaining letters 'den' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eden that I've seen before include "Paradise - ex-prime minister" , "Leading 11 [CONSERVATIVE]" , "Badly need the garden" , "In need of a great garden" , "Adam and Eve's garden" .)
