Thousands of people are on the streets outside Windsor Castle after many of them camped out overnight to grab the best spots to catch a glimpse of Prince Harry and Meghan Markle on their wedding day.
Like many others, Canadian royal-watcher Bernadette Christie spent several rough nights sleeping under the stars.
She says the exhaustion, cold and sore back will all be worth it if she sees the royal couple pass by in their state carriage.
Police and security marshals are out in force to ensure the safety of the tens of thousands of people expected to converge on Windsor during the day.
