The UK government has announced that union and national flags will fly at half-mast on all government buildings until 08:00 BST on the day following the funeral. Union flags on royal buildings, where the Queen is not in residence, will also fly at half-mast.
The Royal Standard, which represents the sovereign and continuation of the monarchy, never flies at half-mast and will be flown at full mast where the Queen is present.
Gun salutes will take place at 12:00 BST on Saturday to honour the duke. Guns at locations across the UK and in Gibraltar will fire 41 rounds at one round every minute for 40 minutes.
Royal Navy ships at sea, including HMS Diamond and HMS Montrose, will also fire the salute, a tribute to the duke, who served as a naval officer during World War Two and held, among other titles, the office of Lord High Admiral.
Funeral Preparations are under for His Royal Highness The Prince Philip, Queen Elizabeth II’s Husband, who died on Friday aged 99.
Details will be announced in the coming days, but it is expected to be a ceremonial event rather than a large state affair usually associated with the death of a monarch.
The public are encouraged to observe the gun salutes from home, online or on television.
Out of respect, the main political parties in England, Scotland and Wales have suspended campaigning for next month’s elections. The House of Commons will sit on Monday for MPs to pay their tributes to the duke.
