As Lumutqueen says, this would be a coronation, not an inauguration. But it is also the enthronement of the Head of the Church of England. So it won't be like the Dutch ceremony. However, I think it will be simpler for practical reasons.
It won't be the same as the one in 1953 in terms of attendees (IMO) because of the changes to the House of Lords, ie not all hereditary peers. All the peers and their wives attended in 1953. And I also think that in these safety conscious days, putting 3 times the capacity into Westminster Abbey won't be allowed either. I should think they have it all worked out already.
