I’m very proud of myself - I have very nearly finished today’s Guardian crossword. Not the quick one, but the cryptic one. I have never managed to finish it before - and I haven’t quite managed it this time either. But I will if you can help me with the four clues I haven’t solved:

Veto for proposal (6) _ O _ B _ D
Party policy won’t be one’s main interest (8) I _ _ _ L _ N _
Having nothing on a dark horse, raised stake finally (4) N _ _ _
A man around here may be taken for a girl (3) R _ O
