A singularly perturbed convectionยฑdiusion problem is considered. The problem is discretised using an upwinded ยฎnite element method on layer-adapted meshes. We establish convergence of almost ยฎrst-order in a weighted energy norm, no matter how small the perturbation parameter. As a corollary we deriv
