The proclamation ceremony is a centuries-old tradition that sees the new monarch announced.
As the nation can never be without a king or queen, as soon as Queen Elizabeth II died on Thursday, her son, Prince Charles, became King.
However, it needed to be confirmed and this is what the proclamation ceremony today will be for.
The event, hailing King Charles III, will take place at 2pm in Market Place.
Local dignitaries will assemble in front of the RYND café for the first such ceremony in 70 years.
Open to the public, it will be led by the borough mayor, Cllr Caroline Smith, and is a short, solemn announcement.
It will open with a short speech by the Revd Canon Richard Lamey from St Paul’s Church on Reading Road. He will explain more about the history of the ceremony, and why it is taking place today.
Cllr Smith will then read the proclamation, ending by saying ‘God save the king’ – a refrain the dignitaries repeat. The crowd then say it.
St Sebastian Wokingham Band will play the first verse of the National Anthem, which is now God Save The King.
There will then be a call from the Commanding Officer of 2499 Wokingham Squadron Air Training Corps calls for three cheers for the new king.
The crowds then disperse.
Wokingham Town Hall is also hosting a book of condolence, and people can sign this up to 3pm today. It reopens tomorrow so people can sign across the week.
And floral tributes can be left in the area where the Christmas tree usually stands.
The request is to remove all cellophane wrappers to ensure that the flowers can be composted afterwards and used to help make a memorial tree.
