Abstract: We give the first example of a locally quasi-convex (even countable reflexive and $ k_\omega $) abelian group $ G$ which does not admit the strongest compatible locally quasi-convex group topology. Our group $ G$ is the Graev free abelian group $ A_G(\mathbf {s})$ over a convergent sequence $ \mathbf {s}$.
