King Charles and Camilla, the Queen Consort, are at Westminster Abbey for their Coronation service.
There are several stages to the service, which is expected to last a little under two hours.
In the first stage – the recognition – King Charles is presented to “the people”, in a tradition dating back to Anglo-Saxon times.
After the service, there will be a second, larger procession before a royal appearance on the Palace balcony.
Around 2,200 people, including the Royal Family, celebrities, faith leaders and heads of state, are in attendance
