| Tuesday 20 October 2230 BST - BBC Two Presented by Jeremy Paxman "We believe that this decision of the IEC is legitimate, legal and constitutional and that it strengthens the path towards democracy." So said Afghan President Hamid Karzai today as he confirmed that he will take part in a run-off for the Afghan presidency against Dr Abdullah Abdullah in two weeks time. Tonight, Lyse Doucet will be reporting for Newsnight from Kabul. We will have the latest on the decision, the international pressure which brought it to fruition, the difficult security issues from a second vote and the all important question of whether Afghanistan ensure that this round is fraud free. Also we have a new film in our series about young people leaving the care system. Tonight, Liz MacKean catches up with Phil, who is turning 18. Phil has been in several foster homes over the years and must now prepare to move on from his latest foster placement and live on his own. Watch a preview of Phil's story here. And we will be looking into claims that the problem of sex trafficking has been exaggerated and that the number of people who have been brought into the UK and forced against their will into prostitution is much smaller than claimed. We hope to be speaking to one of the politicians who pressed for change to sex trade laws in England and Wales. Join Jeremy for all that and more at 10.30pm. |
