Ukraine's second city of Kharkiv has been left without power after the latest wave of Russian strikes targeted energy stations across the country. We speak to Anastasia, a resident of Kharkiv who says she heard several explosions as the strikes began on Friday morning. Also in the programme: President Cyril Ramaphosa of South Africa has been heckled as he addressed his own ANC party conference; and we have a sneak preview of a documentary on one of the most powerful politicians in the United States, Nancy Pelosi, made by her own daughter.
