Let H and G be graph classes. We say that H has the Erd" os-PΓ³sa property for G if for any graph G β G, the minimum vertex covering of all H-subgraphs of G is bounded by a function f of the maximum packing of H-subgraphs in G (by H-subgraph of G we mean any subgraph of G that belongs to H).

Let K(G) denote the clique graph of a graph G. If q is a class of graphs, then define K(W) to be {K(G): G&}. The class QF is called a clique-closed class if V= K(%'). A graph G is said to have the D,-property if G has both the Helly and'the T,-properties. In this paper, we show that the class of D,
