Kirsty Young's castaway is the Egyptian writer and commentator Ahdaf Soueif.

She was the first Muslim woman to be shortlisted for the Booker Prize and, from an early age, her life has been divided between Egypt and Britain. She was among the crowds in Tahrir Square last year, witnessing the uprising at first hand, and describing events for the world's media.

She says: "Every once in a while there would be a surge of a few meters forward, as your friends, who were being killed at the front, gained you those three metres and your job, as the masses, was to move forward and hold the three metres."
