Stand in church, left centre, roughly (7)
I believe the answer is:
'stand in church' is the definition.
(I've seen this before)
'left centre roughly' is the wordplay.
'left' becomes 'l' (common abbreviation).
'roughly' indicates anagramming the letters.
'centre' anagrammed gives 'ectern'.
(Other definitions for lectern that I've seen before include "Desk or stand with a slanted top used to hold text" , "Church reading desk" , "Bible stand" , "Where talk takes place" , "Support for bible in church" .)
