Americans will have no trouble finding Prince Harry and Meghan Markle's royal wedding playing on a screen nearby on Saturday. The real difficulty will be in avoiding it for those surly few who can't stand weddings or royals or both.

But that lot can take themselves off to the wilderness with no Wi-Fi; everybody else will settle themselves in front of their tellys or devices very early in the morning to consume gallons of tea, nosh on crumpets and marvel at the ceremonial magic the British will conjure from the 948-year-old ramparts of Windsor Castle.

More than 2 billion people around the world watched the 2011 wedding of Prince William and the former Kate Middleton at Westminster Abbey in London, according to leading British wedding planning app Bridebook
