Prince William and Prince Harry have slashed the number of guests at the unveiling of Princess Diana's statue, according to reports.

The feuding brothers are said to have significantly reduced the number of attendees at Kensington Palace on July 1 due to Covid.

The event is being held on what would have been the Princess of Wales' 60th birthday.

Diana - William and Harry's mother - was tragically killed in a car crash in 1997.

It is thought that the siblings had hoped for around 100 people to attend the ceremony, according to the Daily Mail.

But the pandemic has forced them to change their plans - meaning just the brothers and relatives of Diana could be there.

The newspaper reports that guests have been told a new date for a larger ceremony will likely be fixed for September.

The move could prove frustrating for many of Diana's friends, who had hoped to reunite the warring brothers.

A rift has grown between William and Harry since the latter moved to the US during 'Megxit'.

He is now living in California with wife Meghan Markle and their two children after quitting the royal family.

The statue event has been dogged by the question of whether Harry would attend, such is the breakdown of the relationship.

The Duke of Sussex jetted back to Britain in April for Prince Philip's funeral, which was held at Windsor Castle.

But, despite reports to the contrary at the time, it has been claimed that he, William and Prince Charles did not meet to talk.

It had been suggested that the trio had sat down and hammered out their differences in the wake of that Oprah interview.

But, writing in an updated version of his book Battle of Brothers, royal historian Robert Lacey quashed any claims of truce.

The Mirror revealed previously that Charles was keen to see Harry after the funeral but his son made it clear to him that "he wasn't sticking around".

And Lacey, whose book is being serialised in the Times, wrote of William and his wife, Kate Middleton: "They told friends that they could see no point in talking to Harry, since any discussion of substance would go straight back to Meghan to be leaked out via Oprah [Winfrey] or some other tentacle of the Sussex network."

The Mirror also revealed earlier this week that Kate will help the brothers put on a united front at the ceremony.

The trio are expected to walk in together, but the brothers will make separate speeches and jointly pay tribute to Diana’s legacy, as well as sculptor Ian Rank-Broadley for his dedication to the project they have been working on since 2017, 20 years after Diana’s tragic death.
