Ad of the day: The Sunday Times - 'Bringing the World to Britain'

Christina Lamb is - in many ways - an unlikely-looking war correspondent but if you watch this film, you'll quickly realise how little someone needs to resemble the stereotype of the battle-hardened tough guy to possess the requisite bravery and fortitude.

This is a mesmerising portrait from a really excellent series and as much as its makers try to persuade us that this isn't really advertising, it possesses a tremendous power which makes you want to support the work of people like Lamb far more effectively than a 30" commercial ever could.
