Worthy Conservative and socialist I put forward (10)
I believe the answer is:
creditable
'worthy' is the definition.
('creditable' can be similar in meaning to 'worthy')
'conservative and socialist i put forward' is the wordplay.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'and' says to put letters next to each other.
'socialist' becomes 'red' (red is a kind of socialist).
'put forward' becomes 'table' (I've seen this in other clues).
'c'+'red'+'i'+'table'='CREDITABLE'
(Other definitions for creditable that I've seen before include "Believable" , "Praiseworthy" , "Deserving of praise" , "Worthy" , "good" .)
