Buckingham Palace has made previously unseen images of the royal public available as part of the monarch’s homage to the Duchess.

According to reports, Prince Edward and Sophie have a very tight bond that has only gotten stronger since Prince Harry and Meghan Markle left their prominent royal roles to move to the US and begin independent lives.

The announcement also coincides with rumors that Sophie may soon play a bigger part in the royal family. King Charles intends to give Sophie the credit she merits, according to a RadarOnline article.

William is also preparing significant preparations for Lady Louise and Viscount James, the offspring of Sophie and Edward.
