Britain's former special envoy to Afghanistan has warned that a sudden withdrawal from Afghanistan without a political settlement could lead to chaos and civil war.
Sir Sherard Cowper-Coles - who was appointed special representative on Afghanistan and Pakistan in March 2009 but stepped down from his position in September 2010 - gave evidence to the Foreign Affairs Committee on 9 November 2010.
He warned that British troops would have to maintain a long-term presence for training and that the Department for International Development would need to be in Afghanistan for 50 years.
He has previously been critical of Nato and US policy, and said talks with the Taliban should have greater priority.
UK forces have been in Afghanistan since the removal of the Taliban government in 2001, following the 9/11 attacks in the US.
