After a long Saturday for millions of Oasis fans in online queues, the culture secretary says surge pricing will be part of the government’s review of the ticket market.       Niall speaks to secondary ticketing site Viagogo on this episode. While it wasn’t part of dynamic pricing, it has offered resale tickets for thousands of pounds since Saturday.   Matt Drew from the company accepts the industry needs a full review while Adam Webb, from the campaign group FanFair Alliance, explains the changes it would like to see.  Later, our data and forensics correspondent Tom Cheshire tells Niall about how a rise in online propaganda has helped the Afghan branch of Islamic State become “the greatest external terror threat”. It’s been linked to the concert hall attack in Moscow and the plot to disrupt Taylor Swift gigs in Austria.  Producers: Soila Apparicio, Emma Rae Woodhouse Editor: Paul Stanworth
