Those people without exception find the way to the Palace (3,4)
I believe the answer is:
the mall
'the way to the palace' is the definition.
(road leading to Buckingham Palace)
'those people without exception' is the wordplay.
'those' becomes 'them'.
'people without exception' becomes 'all'.
'them'+'all'='THE MALL'
'find' acts as a link.
(Other definitions for the mall that I've seen before include "way in London" , "Route to Buckingham Palace" .)
