Vikings at British Museum; John Carter Cash; 37 Days

With John Wilson,An enormous Viking longboat - the biggest ever discovered - is the central piece in the British Museum's new exhibition about the Viking era. Taking pride of place in the museum's newly-constructed Sainsbury Exhibitions Gallery, the longboat is surrounded by other artefacts of warfare, as well as many treasures that the Vikings created - or looted. A year ago, British Museum director Neil MacGregor took John round the work-in-progress when the gallery was still a building-site; now he explains how the new space will aid future displays, and curator Gareth Williams gives John a tour of the ferocious Viking weaponry and stunning jewellery.As part of a BBC series marking the centenary of World War One, Ian McDiarmid (Star Wars) and Tim Pigott-Smith (Spooks) star in political thriller 37 Days.
