I also worried about Conservative Party (6)
I believe the answer is:
social
'party' is the definition.
(social is a kind of party)
'i also worried about conservative' is the wordplay.
'worried' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'i'+'also'='ialso'
'ialso' is an anagram of 'soial'.
'soial' placed around 'c' is 'SOCIAL'.
(Other definitions for social that I've seen before include "Liking companionship" , "Relating to human groups" , "Gregarious; gathering" , "Public servant caring for the underprivileged" , "Informal gathering" .)
