24d Greek island starts to make it with the Spanish. M?L?S
Looks like Milos but "the Spanish" would indicate "EL". Can't see it.
COTW Singer in company, soprano ultimately? (8, singer = rat)
Presume the setter is giving a clue with singer = rat i.e. a gang member who is arrested and "sings" is a rat, but it doesn't help me with the answer! I was thinking maybe CONTRALTO but one letter too many.
