We introduce a new asymmetry in the decay t -> W b -> l nu b, which is shownto be directly proportional to the polarisation of the top quark along a chosenaxis, times a sum of W helicity fractions. The latter have already beenprecisely measured at the Tevatron and the Large Hadron Collider. Therefore,this new asymmetry can be used to obtain a model-independent measurement of thepolarisation of top quarks produced in any process at hadron or leptoncolliders.
