I've served on Labour's frontbench for much of the last 20 years, under four leaders. They all had flaws. And when I spoke to Jeremy today he agreed that that he, and we all, must do better. However, all four were elected leaders of our Party. Jeremy Corbyn's re-election earns him the right to lead Labour again, and the right to expect backing from Labour MPs. We must now pull together. Our task is to take on the Tories and win over the public.
