    "abstract": "We show that bipartite entanglements involving non-orthogonal states are {\\it\nnecessarily nonmaximally} entangled, however {\\it small} the non-orthogonality\nmay be. How the deviation from maximal entanglement is related to\nnonorthogonality is quantified by using two independent measures of\nentanglement corresponding to the violation of Bell\u0027s inequality and the\nentropy measure respectively. This result is true even if one of the subsystems\nhas orthogonal states. An application of this is that a maximal violation of\nBell\u0027s inequality in entangled neutral kaons is not possible in the presence of\nCP violation.",
