Newsnight

In-depth investigation and analysis of the stories behind the day's headlines, presented by Gavin Esler. Liz MacKean has the latest film in the Leaving Care series, focusing on the fortunes of young people reaching 18 and leaving the care system. She looks at the system in Sweden to see how it compares with the UK, meeting Sophia and Angelica, who grew up in care in Sweden and now live independently. There's a report on the day's events at the UN climate summit in Copenhagen, plus a report on the decision by the British government to buy 22 new Chinook helicopters and other equipment for Afghanistan - funded by making cuts elsewhere in the defence budget.
