Prejudiced Conservative supporting Germany is almost deplorable (14)
I believe the answer is:
discriminatory
'prejudiced' is the definition.
(synonyms)
'conservative supporting germany is almost deplorable' is the wordplay.
'conservative' becomes 'tory' (informal term for a Conservative Party member).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'germany' becomes 'd' (international vehicle registration code).
'almost deplorable' becomes 'crimina' (I can't justify this - if you can you should give a lot more credence to this answer).
'd'+'is'+'crimina'='discrimina'
'tory' after 'discrimina' is 'DISCRIMINATORY'.
Can you help me to learn more?
(Other definitions for discriminatory that I've seen before include "Biased" , "Showing prejudice" , "showing bias" , "Partial" .)
