We show that Sarnak's conjecture on Mobius disjointness holds in every uniquely ergodic model of a quasi-discrete spectrum automorphism. A consequence of this result is that, for each non constant polynomial P is an element of R[x] with irrational leading coefficient and for each multiplicative function. upsilon: N -> C, vertical bar upsilon vertical bar <= 1, we have 1/M Sigma(M <= m < 2M) 1/H vertical bar Sigma(m <= n < m+H) e(2 pi ip(n)) upsilon(n)vertical bar -> 0 as M -> infinity, H -> infinity, H/M -> 0.
