The UK government wants to tell a positive economic story about trade. The problem is Saudi Arabia, a country investing billions in Britain, has been given a "deplorable human rights record" by groups like Human Rights Watch. Our Saudi Arabia bureau chief Christine Burke explains how Riyadh has emerged as a global player, why five UK ministers are currently there with the largest business delegation in a decade, and what both nations are trying to achieve by their improving relations.
