Politics Pen returns, this time giving Newsnight viewers a chance to face our political animals and pitch their policy ideas on how we can raise more money from taxation, Dragons' Den style. There's a report on the five British soldiers in Afghanistan who died at the hands of the Afghan policeman they were mentoring. Plus David Grossman reports on the Conservative's cast iron guarantee for a referendum on the Lisbon Treaty. Presented by Emily Maitlis.
