Jackson of "A Touch of Class” (6)
I believe the answer is:
glenda
'jackson of a touch of class' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for glenda that I've seen before include "--- Jackson, Br. actress" , "- - Jackson, Hampstead MP" , "-- Jackson, actress and former MP" , "Girl" .)
