Britain's billionaires – all 117 of them – have an eye-watering fortune of £325bn between them.
To put that in perspective, if it were shared out across the country, each person would pocket £5,000. That's enough for a deposit on a flat in Newcastle. (In London, that's really only going to get you a garage or parking space)
On the other hand, it would take the average worker almost 12m years to earn the entire wealth of Britain's billionaires.
