Summary: A mesmerising speech from a great South African churchman: the retirement of Archbishop Tutu is marked by Allan Little; Ian Pannell on the increasingly unsafe roads of Afghanistan; Farhana Dawood is in Leipzig noting the continuing divisions between Germans from the east and west of the country; Martin Patience tells us how the Chinese government is having to consider the implications of an ever-older population while Christine Finn is in the Northern Irish fishing village of Ardglass tasting one of the "silver darlings" on which the port has built its reputation.
