Queen Victoria maybe is first in shop (9)
I believe the answer is:
stationer
'shop' is the definition.
(I've seen this before)
'queen victoria maybe is first' is the wordplay.
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'victoria maybe' becomes 'station' (Victoria is a London train station).
'is first' says to put letters next to each other.
'er' after 'station' is 'STATIONER'.
'in' is the link.
(Other definitions for stationer that I've seen before include "has what writer needs" , "Retailer of writing materials etc" , "I supply rulers: for example" , "Writing-materials shop" , "Shopkeeper" .)
