John's Theorem for an Arbitrary Pair of Convex Bodies

We provide a generalization of John's representation of the identity for the maximal volume position of L inside K, where K and L are arbitrary smooth convex bodies in ℝn. From this representation we obtain Banach–Mazur distance and volume ratio estimates.
