As you will be aware the national proclamation has been made today confirming His Majesty King Charles III as the new King. Following this, local proclamation events can occur when the wording of the national proclamation can be read out in local areas.
The High Sheriff of Buckinghamshire, Debbie Brock will be announcing the proclamation in Buckinghamshire tomorrow at 1pm in the marketplace in Aylesbury. This is a public event and everyone is welcome to attend. It will also, subject to connectivity, be broadcast on Facebook, which can be viewed here Buckinghamshire Council | Facebook I understand that the MK event takes place at 3pm.
The proclamation wording can be viewed here https://www.college-of-arms.gov.uk/2-coa/78-the-accession-proclamation. Parish Councils are not obliged to make a proclamation but may do so if they wish, only after completion of the County Proclamations.
We have also been advised of a tweak to the guidance on the flying of flags. The Union flag should be flown at full mast this morning and then flown again at half-mast from 1.30pm tomorrow (Sunday) unless you are holding a proclamation event, in which case the flag should be flown at half-mast once your event has finished.
