AbstractWe consider the following problem as a generalization of that solved by Tura´n's theorem. Let t and n be positive integers with n⩾t⩾2. Determine the maximum number of edges of a graph of order n that contains neither Kt nor Kt,n−t as a subgraph. For n=2t, it is solved by Brualdi and Mellendorf (1994). We solve it for n=2t + 1
