The media giant News Corp. announced yesterday that it would close its most successful tabloid paper, News of the World,  over claims its journalists hacked the private phones of celebrities, crime victims, bereaved military families and people involved up in the 2005 London bombings  –  a terrorist attack that killed 52 people. Paul Dadge was present at the London bombings. A striking photograph of him  helping a woman burnt in the blast  was become one of the most iconic images from the attack. He explains how this week he was notified by police his messages may have been hacked by journalists. We also speak with  Brian Stelter,  media correspondent for our partner,  The New York Times,  about how the closure may impact on the rest of the News Corp. empire.
