  We give a new proof of the existence of Klyachko models for unitary
representations of ${\rm GL}_{n}(F)$ over a non-archimedean local field $F$.
Our methods are purely local and are based on studying distinction within the
class of ladder representations introduced by Lapid and Minguez. We classify
those ladder representations that are distinguished with respect to Klyachko
models. We prove the hereditary property of these models for induced
representations from arbitrary finite length representations. Finally, in the
other direction and in the context of admissible representations induced from
ladder, we study the relation between distinction of the parabolic induction
with respect to the symplectic groups and distinction of the inducing data.
