Another moment in the history of Westminster Hall

The new King makes his first trip to Parliament today as Sovereign.
And what a spot he is heading to.The oldest part of the Palace of Westminster: Westminster Hall.
I will be commentating as part of a special programme on Radio 4 at 10am marking the ceremony, and so I’m lucky enough to have a ticket.
It is a spectacular building, often forgotten about beyond Westminster, as it’s not regularly televised in the way both the Commons and the Lords are.
It hosted Henry VIII's Coronation Banquet and the trial of Guy Fawkes.
It's hosted addresses by France's war-time leader Charles de Gaulle and Nelson Mandela.
This then, today, is just the latest moment of note in Westminster Hall, since it was built in 1097.
This morning, it is the latest staging post in the choreography of constitutional ritual.
Around 900 MPs and members of the House of Lords are expected.
They'll witness the processions, a trumpet fanfare, the National Anthem - and the speakers of both Houses of Parliament, Sir Lindsay Hoyle and Lord McFall, addressing and offering condolences to the King and the Queen Consort.
They'll also pledge loyalty to the new Sovereign.
