Prince Philip, the Duke of Edinburgh, died at the age of 99.
The Queen's consort was admitted to the hospital earlier this year due to heart troubles. On Friday, April 9, the British royal family confirmed that he had passed away at Windsor Castle.
The palace has now launched the so-called "Operation Forth Bridge" - the codename for the set of post-mortem national procedures in place following the death of royalty.
So what happens next? Let's take a look at those very procedures, step-by-step.

The plan of procedures first dictates that Lord Chamberlain Baron Parker of Minsmere, consult with the Prime Minister and the Queen to plan the announcement of the news.
The Press Association and the BBC are the first members of the media to be told the news first, while Buckingham Palace will also make an announcement on its own social media platforms.
The Prime Minister then delivers a statement, and yesterday Boris Johnson spoke to the press about the death of the Duke outside number 10 Downing Street.
Johnson praised the Prince’s work with young people through the Duke of Edinburgh’s Award scheme, as well as his years of naval service.

The United Kingdom will now enter into a national period of mourning, with all union flags lowered to half-mast on royal buildings where the Queen is not in residence.
Newsreaders and public broadcasters will wear black during this time, while others, such as the BBC, suspending programming for a short interval.
The other members of the royal family will mourn Prince Philip for several weeks, with the Queen confirming that her own period of official bereavement will last at least eight days.
Most of the monarch's official engagements will be either postponed or canceled at the Queen’s discretion during this time.

Although Prince Philip is entitled to a state funeral, The Independent reports that he has previously professed a desire for a simple ceremony rather than a grand affair.
Now it has been confirmed that the Duke will lie in rest at Windsor Castle. His funeral is due to take place at St George’s Chapel at Windsor Castle.
