Newsnight - Season 2011 Episode 104

With more doubts raised today on the government's ability to control immigration, one group who are being targeted are students who wish to study here. But can the UK afford to turn many of them away? Tonight we will debate whether the crackdown on student visas keeps the best and the brightest out, or simply closes one big immigration loophole. As the E-Coli bug claims more victims Susan Watts reports on how worried should we be about this new and powerful strain, and we talk to Professor Hugh Pennington, who led inquiries into two E-Coli outbreaks in the UK. And 1980s architecture - iconic buildings like London's Broadgate Centre and the Law Courts in Truro - is starting to turn 30. Love them or loathe them, this means they can now apply for listed heritage status. But should they be saved? Tonight we have an authored film from Wayne Hemingway on the proposed listing of iconic and controversial early '80s developments. Before you see that film, check out this classic piece of BBC archive we've uncovered of Prince Charles talking about 1980s architecture.
