Ainsworth: UK troops 'force for good'

Defence Secretary Bob Ainsworth has reaffirmed the UK's commitment to operations in Afghanistan.

In his first major speech since his promotion, Mr Ainsworth stressed that Britain cannot afford to waver in its mission, but admitted that it was not likely to be completed soon.

The death of the seventh British soldier killed in the country in seven days was also confirmed.
