At the top, the Conservative leader needs a break (5)
I believe the answer is:
crest
'at the top' is the definition.
I can't judge whether this definition defines the answer.
'conservative leader needs a break' is the wordplay.
'leader' indicates taking the first letters.
'needs' says to put letters next to each other.
'a break' becomes 'rest' (a rest is taking a break).
The initial letter of 'conservative' is 'c'.
'c'+'rest'='CREST'
'the' is the link.
Can you help me to learn more?
(Other definitions for crest that I've seen before include "Top (of wave etc)" , "Peak - comb" , "Top point of hill or wave" , "Surmount" , "Top of a ridge/wave" .)
