Member in dailies every so often making claim (6)
I believe the answer is:
allege
'claim' is the definition.
(to allege something is to make a claim)
'member in dailies every so often' is the wordplay.
'member' becomes 'leg' (member can mean a limb).
'in' means one lot of letters goes inside another.
'every so often' indicates alternate letters.
The alternate letters of 'dailies' are 'ale'.
'leg' placed within 'ale' is 'ALLEGE'.
'making' acts as a link.
(Other definitions for allege that I've seen before include "Declare without actual proof" , "Claim (a person is guilty)" , "Make a claim without proof" , "Make accusation without proof" , "Declare without being able to prove" .)
