We combine the results of Bartal [Proc. 37th FOCS, 1996, pp. 184-193] on probabilistic approximation of metric spaces by tree metrics, with those of Klein, Plotkin and Rao [Proc. 25th STOC, 1993, pp. 682-690] on decompositions of graphs without small K s,s minors (such as planar graphs) to show that
