Annotation	The effects of strong gravity on the polarization of the Compton reﬂection from an X- ray illuminated accretion disc are studied. The gravitational ﬁeld of a rotating black hole inﬂuences Stokes parameters of the radiation along the propagation to a distant observer. Assuming powerlaw illumination of the disc by corona, the degree of polarization is examined as a function of the black hole spin, observer’s inclination angle and height of the primary source.
