Could this be the end for the monarchy in Great Britain?

T may be that we are witnessing the beginning of the end of the monarchy in Britain. It is an institution which time has passed by. When Australia leads the way and becomes a republic that will be the catalyst for a great reset in the UK.

- William Loneskie

A new beginning. The country will be renamed Britain instead of the UK, with of course a new secular anthem rather than the mournful dirge God Save the King, and GB would return as the international moniker. The flag would remain as is.

Moving from a monarchy to a republic would present challenges and problems, of course. For example, would the RAF continue to be named thus, and would the Royal Navy be renamed the British Navy and the prefix HMS before warships' names removed?
