The Queen is the UK’s longest-serving Monarch in its history and throughout the decades Prince Charles has been preparing to follow her reign as King.

Sadly, the Queen has fallen ill at Balmoral Castle, with doctors currently giving her medical supervision during this worrying time.

Prince Charles, along with Prince William, are both heading to her Scottish home now, as the UK fears the worst.

In the tragic circumstance of the Queen’s death, the UK has a plan in place that will ensure a smooth transition process.

This is known as Operation London Bridge, which was devised by ministers and the Monarch herself. However, if she dies in Scotland it is known as Operation Unicorn.

It lists the country’s 12-day mourning period, which will involve the funeral, along with Charles’ official succession ceremony.

Here is everything you need to know about Charles’ succession.

When will Prince Charles be crowned King?

Upon the death of the Queen, Prince Charles will immediately be crowned King of the UK, Commonwealth and Overseas Territories.

It is something Charles is prepared for, as he is the longest-waiting heir apparent in the Royal Family’s history.

An ‘Accession Council’, which consists of the group of advisors known as the Privy Council, will then convene at St James Palace in London.

They will then formally recognise Charles as King and proclaim him the new monarch of the UK.

Charles will then take an oath to preserve the Church of Scotland because the ruling monarch is only the head of the Church of England.

At this stage, Parliament will be recalled for its members to take an oath of allegiance.

What will Prince Charles new title be?

Following the death of the Queen and his succession of the throne, Prince Charles will be known as King Charles III.

However, some superstitions may get in the way of this name, as one of the previous King Charles’ came to unfavourable end.

King Charles I was beheaded, and the monarchy abolished in 1649, though his son was restored to the throne and was generally liked as a king.

More pragmatically, the UK public and the rest of the world has known Prince Charles under that title his entire life.

It is thought he may choose to retain it even when he becomes King.
