Tonight on Newsnight with Kirsty Wark we have an exclusive interview with His Royal Highness Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud - the second biggest investor in News Corporation. David Grossman will be taking us through the events of the day. Tim Whewell has a report on how the contagion of the Murdoch brand is spreading around the world, and particularly to the US. And we will be discussing whether this phone-hacking scandal will accelerate the demise of newspapers, or blow over.
