## Abstract

The most prominent special case of our main result is that the free centre-by-(nilpotent of class (c-1))-by-abelian groups F/[\gamma_c(F'),F] are torsion-free whenever c is divisible by at least two distinct primes. This is in stark contrast to the case where c is a prime or c=4, where these relatively free groups contain non-trivial elements of finite order.
