Summary: In this paper we show that two skew diagrams $\lambda / \mu $ and $\alpha / \beta $ can represent the same multiplicity free skew character $[ \lambda / \mu ]=[ \alpha / \beta ]$ only in the the trivial cases when $\lambda / \mu $ and $\alpha / \beta $ are the same up to translation or rotation or if $\lambda = \alpha $ is a staircase partition $\lambda =( l, l - 1,\cdots ,2,1)$ and $\lambda / \mu $ and $\alpha / \beta $ are conjugate of each other.
Keywords: keywords skew characters, symmetric group, skew Schur functions, Schubert calculus
