A year ago, the Commonwealth Games looked dead and buried. The Australian state of Victoria had pulled out of hosting the 2026 edition due to spiralling costs, and in Canada, the province of Alberta had stepped back from bidding for the 2030 edition. But now Scotland’s biggest city, Glasgow, has ridden to the rescue, agreeing to host the 2026 Games. It says its scaled back, lower-budget model for doing so could encourage poorer countries to do the same in the future. How realistic is that? Is Glasgow 2026 the last hurrah for an anachronistic sporting event, inextricably tied to the British empire, or does it really represent a fresh start?(Picture: A Commonwealth Games Glasgow 2026 delegation in Glasgow, UK.

The Suez Canal was once one of the busiest global shipping routes – a third of the world's shipping containers normally pass through it. Since the Houthis began to attack passing ships last year, the volume of vessels going through has declined rapidly.The canal is run by the Egyptian government, and fewer ships means less foreign currency coming into the economy.And it’s not just revenue from ships that Egypt is losing, it’s also losing tourists, as many people cancel their trips and spend their dollars elsewhere. We speak to businesses in Cairo to see how they’re being impacted by these changes, and ask, as Egypt loses out, are other countries winning?
