We solve the linearised Vlasov-Fokker-Planck (VFP) equation to show that heat
flow or an electrical current in a magnetized collisional plasma is unstable to
the growth of a circularly polarised transverse perturbation to a zeroth order
uniform magnetic field. The Braginskii (1965) transport equations exhibit the
same instability in the appropriate limit. This is relevant to laser-produced
plasmas, inertial fusion energy (IFE) and to dense cold interstellar plasmas.
