King Charles III declared a period of national mourning for UK following the death of the Queen - which means there are certain things the public can and can't do.
The 73-year-old confirmed the national mourning will continue until seven days after the Queen's funeral, which is set to take place at Westminster Abbey on Monday, September 19, at 11am.
Flags are being flown at half-mast by businesses and on Government buildings as a mark of respect - with many newsreaders dressed in black.
