William and Kate have sent a strong message to Harry and Meghan in a ‘show of solidarity’ in their first joint public appearance since the Sussexes return.

Prince William and Kate Middleton carried out their first joint engagement since the summer to mark World Suicide Prevention Day at Everton’s home ground in Liverpool.

Royal expert Duncan Larcombe has noted that this visit caught attention for a number of reasons and not only because Kate decided to join her husband on what was expected to be a solo outing.

He claimed the engagement was “the regal equivalent of flexing their combined muscles in a show of solidarity that sent a message to the Sussexes.”

Larcombe continued: “William and Kate clearly want to ensure they take centre stage as they brace for Harry and Meghan to make their next move.”

The royal expert added that Kate was “throwing down the gauntlet to her brother- and sister-in-law” as the couple will have been determined to make a statement.

Kate is also expected to join Prince William in Mumbai in November for The Earthshot Prize ceremony, the pair’s first overseas official engagement in four years.

Again, the timing of this trip appears another part of the Windsors’ “strategy” to signal their strength to the Sussexes.

The couples, who were formerly known as the fantastic four, have seemingly been in a public feud for several years, only worsening since Harry and Meghan stepped down as royals and started to make claims against William and Kate to the media.

Now, following the pair’s move back to the UK the question of reuniting has been on everyone’s lips, as it is thought Harry and William will have no choice but to be in one another’s company.

These joint enagagements from William and Kate are sending a message to Harry and his wife before they are all made to reconvene, with Larcombe claiming they are meetingm “the challenge posed by Harry and Meghan head-on.”
