  Recently, the accretion geometry of the black-hole X-ray binary Cyg X-1 was
probed with the X-ray polarization. The position angle of the X-ray emitting
flow was found to be aligned with the position angle of the radio jet in the
plane of the sky. At the same time, the observed high polarization degree could
be obtained only for a high inclination of the X-ray emitting flow, indicating
a misalignment between the binary axis and the black hole spin. The jet, in
turn, is believed to be directed by the spin axis, hence similar misalignment
is expected between the jet and binary axes. We test this hypothesis using very
long (up to about 26 years) multi-band radio observations. We find the
misalignment of $20^\circ$--$30^\circ$. However, on the contrary to the earlier
expectations, the jet and binary viewing angles are found to be similar, while
the misalignment is seen between position angles of the jet and the binary axis
on the plane of the sky. Furthermore, the presence of the misalignment
questions our understanding of the evolution of this binary system.
