Regularly cleans Tories' meeting place (6)
I believe the answer is:
centre
'meeting place' is the definition.
'regularly cleans tories'' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'cleans'+'tories'='cleanstories'
The alternate letters of 'cleanstories' are 'CENTRE'.
(Other definitions for centre that I've seen before include "and this may follow 26, 25 [LEFT RIGHT]" , "- forward; - punch" , "Recent (anag)" , "Midpoint" , "See 24" .)
