Since 2006, on a conservative estimate, it has cost £15m a day to maintain Britain‘s military presence in Helmand province. The equivalent of £25,000 will have been spent for every one of Helmand‘s 1.5 million inhabitants, more than most of them will earn in a lifetime, it says.

By 2020, the author of a new book says, Britain will have spent at least £40bn on its Afghan campaign, enough to recruit over 5,000 police officers or nurses and pay for them throughout their careers. It could fund free tuition for all students in British higher education for 10 years.
