Abstract
We propose that in QCD with dynamical quarks, colour deconfinement
occurs when an external field induced by the chiral
condensate strongly aligns the Polyakov loop. This effect sets in at the
chiral symmetry restoration temperature 
and thus makes
deconfinement and chiral symmetry restoration coincide. The predicted
singular behaviour of Polyakov loop susceptibilities at is
shown to be supported by finite temperature lattice calculations.
