2d: CON (criminal) G(E)AL (girl taken E(nglish) in)
Don't get 6d: I have D?U?S, so possibly DRUGS
20a: China possibly to one to back who supports Bush (6)
I have ?R?T?A, which could be PRO (supporter) TEA (bush) - but that's not defined by 'china'. A PROTEA can be a bush, but I can't parse the clue to make give me TEA from 'china'.
