Queen Elizabeth II’s death will be called Operation London Bridge in the United Kingdom, but there will be a different term used if she dies while she’s in Scotland.

Millie Bull, a journalist for Express, said that the secret strategy that will be put in place will be called Operation Unicorn. It will involve the immediate suspension of business at the Scottish Parliament.

The suspension will reportedly be put in place to allow authorities to prepare for a state funeral that is expected to become a global event. A source from Her Majesty’s home in Scotland, Holyrood Place, said that the monarch dying north of the border could result in thousands of people from across the globe flying to the region.

It was during last month’s meeting that it was announced that there is a secret strategy being prepared in case the Queen dies. The revelation came from the senior staff at Holyrood called the Scottish Parliament’s Leadership Group (LG).

“LG received an update on planning for Operation Unicorn – the death of Her Majesty the Queen while in Scotland. The primary focus was on the impacts on staffing and the specific impacts depending on timing,” the source said.

But the secret code name was actually first mentioned in the Parliament’s online papers two years ago when LG agreed to set up a resilience board for disruptive incidents. London Bridge operation and Unicorn were mentioned.

Meanwhile, Operation London Bridge is the secret code used to refer to the Queen’s demise. It was put in place in the 1960s, but it is also updated a couple of times every year.

The code name will also be used to inform civil servants that the Queen has died instead of making the announcement directly. The Queen’s private secretary will be the first official to deal with the news of Her Majesty’s death. The private secretary will also be responsible for contacting the Prime Minister.
