Excerpt:
David Cameron has apologised for "any misunderstanding" after describing a former imam as a supporter of the Islamic State group.
He accused Suliman Gani in Parliament of backing the militant group as he questioned Sadiq Khan's judgement in sharing a platform with him.
Mr Gani has said claims he backs IS are defamatory and must be retracted.
Earlier on Wednesday, Defence Secretary Michael Fallon apologised for making similar claims.
