Christian charity Hope for Justice has encouraged those appalled by the Libyan slave trade (see World article no 2) to take action. They produced a petition asking for the Government to put pressure on Libya to stop enslavement of Africans; by 30 November, 90,000 people had signed it. Also a national anti-slavery march has been organised for 9 December. Protesters will meet in Belgrave Square at 12 noon and walk peacefully to the Libyan embassy. The march will also raise people’s awareness that globally 24.9 million people are held in slavery. International Organisation for Migration has helped 13,000 people to get out of detention centres in Libya and 8,000 in Niger, but that is the tip of the iceberg.
