Correspondents' stories: Jeremy Bowen on the effect in Egypt of the upcoming trials of senior figures from the Muslim Brotherhood; you could write the history of the South Pacific as a succession of arrivals of powerful, foreign vessels in palm-fringed lagoons, according to John Pickford in Tonga; the Sudanese capital Khartoum 'changed forever' after the recent riots in the capital - that's what James Copnall's been hearing in Khartoum; Linda Pressly's been to the Spanish city of Melilla, on the north coast of Morocco, to meet the so-called 'mule women' and find out why they're prepared to shoulder such heavy loads and Russians have never been famous for their smiles, but Jamie Coomarasamy's wondering if times have changed and they're now no longer trying to keep a straight face! The programme is produced by Tony Grant.
