Newsnight - Season 2011 Episode 120 24/06/2011

Tonight, we have an exclusive with hacking collective LulzSec, who have been explaining their agenda to Susan Watts. And off the back of that piece we will be talking to former US head of Homeland Security Michael Chertoff and James Lyne - a computer expert who hacks for security companies to test their security. Tim Whewell has an update on our story this week that Syrians protesting against the Assad regime in London say they have been intimidated by officials from their home country. Plus, what does the news that home furnishings retailer Habitat has gone into administration, with only three British stores assured of survival, say about Britain's sense of style today? We will be speaking to designer and Habitat's former style director Tom Dixon and the Editor of Elle Decoration Magazine, Michelle Ogundehin. And Michael Crick is still in Brussels where European Union leaders have gathered for a second day of summit talks dominated by the Greek debt crisis, which is threatening the stability of the 17-nation eurozone. UK Prime Minister David Cameron said today that he had received assurances that Britain would not be called upon to contribute to EU financial support for Greece. Tonight Michael will ask if this is the moment that Britain should redefine its relationship with Brussels and the Union.
