Cuthbert, less bold, quivering somewhere in Low Countries (7)
I believe the answer is:
utrecht
'somewhere in low countries' is the definition.
'cuthbert less bold quivering' is the wordplay.
'less' indicates named letters should be taken away.
'bold' becomes 'b' (abbreviation).
'quivering' is an anagram indicator (letters shake or quiver into a new order).
'cuthbert' with 'b' taken away is 'cuthert'.
'cuthert' anagrammed gives 'UTRECHT'.
(Other definitions for utrecht that I've seen before include "Netherlands province" , "The curt (anag) - city in the Netherlands" , "Dutch city where treaty was signed in 1713" , "City of historic treaty, 1713" , "Netherlands city, scene of 1713 Treaty" .)
