	Fully Supersymmetric CP Violation	

	----------------------------------------------------

				ABSTRACT


    Recently it has been demonstrated that large phases in softly broken
    supersymmetric theories are allowed by electric dipole moment 
    constraints, and are motivated in some string models. Here we consider 
    whether large soft phases in the supersymmetry breaking sector may be the 
    dominant (or only) source of all CP violation, and demonstrate that 
    $\epsilon$ and $\epsilon'/\epsilon$ can be described. We show that in 
    the presence of large phases the SUSY contribution to the B system can 
    be large and dominant, leading to predictions for $b \to s \gamma$, 
    $\sin2\beta$, and $\sin2\alpha$. In this framework 
    $\sin 2 \beta/\sin 2\alpha=-1$, and the unitarity triangle does not close.
