Travelling elite carrying National Trust permit (7)
I believe the answer is:
entitle
'permit' is the definition.
(I've seen this in another clue)
'travelling elite carrying national trust' is the wordplay.
'travelling' indicates anagramming the letters.
'carrying' means one lot of letters goes inside another.
'national trust' becomes 'nt'.
'elite' anagrammed gives 'eitle'.
'eitle' placed around 'nt' is 'ENTITLE'.
(Other definitions for entitle that I've seen before include "Name; enable" , "Call; permit" , "Furnish with a right or claim" , "Name; empower" , "Allow" .)
