Artless politician caught in web of lies (6)
I believe the answer is:
simple
'artless' is the definition.
(similar in meaning)
'politician caught in web of lies' is the wordplay.
I cannot really understand how this works, but
'politician' could be 'mp' (Member of Parliament) and 'mp' is located in the answer.
an anagram of 'lies' is 'sile' which is present in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for simple that I've seen before include "Penniless pie seeker" , "Uncomplicated; herb" , "The opposite of difficult or elaborate" , "Mean" , "Plain and uncomplicated" .)
