Church bells around the country will ring out at noon to mark the Queen's death.
The Church of England is encouraging parish churches, chapels and cathedrals to ring their bells for an hour from noon on Friday September 9. As a mark of respect, bells will be muffled where possible.
Flags will be flown at half-mast until the day of the funeral, other than for a short period on Saturday after Charles III is formally proclaimed as king.
