Queen Elizabeth will reach a big milestone in her monarchy this weekend.

What milestone is Queen Elizabeth celebrating?

On Saturday 18 July, the Queen will have been monarch for 68 years, five months and 12 days.

This means she has reigned for 25,000 days, which is almost 1,800 days longer than the previous record set by her great-great-grandmother, Queen Victoria.

Back in 2015, Queen Elizabeth overtook the record of 23,226 days, 16 hours and 30 minutes set by the late Queen Victoria to become the country's longest-reigning monarch.

Though she has admitted that the royal record was not one she particularly aspired to achieve.

She said at the time, "Inevitably a long life can pass by many milestones. My own is no exception."

It's thought Her Majesty will celebrate the day privately at Windsor Castle, where she is isolating with her husband Prince Philip.

The Queen is set to return to royal duties today when she welcomes Captain Sir Tom Moore to Windsor Castle for a special investiture ceremony.

Announcing the news earlier this week, Buckingham Palace said: "During the ceremony, the Queen will use the sword that belonged to her father, George VI and will award Captain Sir Thomas Moore with the insignia of Knight Bachelor."

The hero of the nation raised over £33 million for the NHS by walking laps of his Bedfordshire garden, despite setting his target at just £1000.

The war veteran will be given the honorary title by the Queen during the private ceremony at Windsor Castle, with no access for viewing by the public.
