Policing and Crime Bill

Before the noble Viscount sits down, is the point not that the complainant may say that the person who allegedly assaulted him or her is a stranger but may have an oblique motive for so saying? How is the defendant therefore able to defend himself or herself without being able to know who the accuser is? It is a palpable injustice which was not covered, I regret, by the passionate speech by the noble Lord, Lord Wigley, which omitted that crucial point.
