Princess Kate could hold the key<\/a> for a reconciliation between warring brothers Prince William and Prince Harry<\/a> as she plays the role of \u2018peacemaker\u2019, according to a new documentary.<\/p>\n The Duke of Sussex<\/a> and the Prince of Wales<\/a> have been locked in a bitter rift for several years, largely perpetuated by Harry\u2019s willingness to share the secrets of the royal family<\/a> since quitting the Firm in 2020.<\/p>\n Now, with Harry\u2019s job prospects in America drying up, a new documentary has explored what it might look like if Harry were to be welcomed back into the royal family once his older brother ascends the throne.<\/p>\n READ MORE: Prince Harry ‘stokes William war with revenge move that’s left friends furious’<\/a>READ MORE: Sarah Ferguson’s outrageous ‘Plan B’ as she ‘plots dramatic return from exile’<\/a> Speaking on the new Channel 5 programme titled The Jobless Prince: What Will Harry Do Next?, Daily Mail royal expert Charlotte Griffiths believes the key to Harry rebuilding his relationship with William in any capacity lies with his sister-in-law: Princess Kate<\/a>.<\/p>\n Griffiths said: \u201cI think Harry could get around the William problem if he got Catherine onboard. If Catherine played peacemaker, which I think she would be open to as she is, or was, quite fond of Harry.\u201d<\/p>\n While the royal expert believed there could be some hope for Harry and William\u2019s relationship, she also declared that it is extremely unlikely Harry will ever be welcomed back as a working royal when William is King. She said simply: \u201cWilliam will not have his brother back in the royal family when he is on the throne.\u201d<\/p>\n There have been several times over the years where the Princess of Wales has solidified herself in the peacemaker role <\/a>within the royal family, particularly when it comes to William and Harry, who have been at odds for more than half a decade.<\/p>\n At the funeral of Prince Philip<\/a> in April 2021, the royals walked back to WIndsor Castle on foot following the service in St George\u2019s Chapel. Kate, William and Harry were seen chatting as they left the Chapel – before Kate quietly dropped behind allowing the brothers to talk.<\/p>\n Speaking at the time, Brian Hoey, <\/a>who has written a biography of Prince William<\/a>, told The Sun: \u201cThey say cometh the hour, cometh the man. But in the Royal Family’s case, it\u2019s a woman. Thank God for Kate \u2014 she is the rock the monarchy will depend on. On Saturday, she behaved absolutely impeccably.\u201d<\/p>\n Kate\u2019s peace-keeping role stems back to before Harry and Meghan quit the royal family in 2020, with reports claiming that she advised Harry to extend an olive branch to William in 2019 to mend their fractured relationship.<\/p>\n At Easter that year, Kate tried to repair \u201ca complete and utter breakdown of communication\u201d between the brothers. Her advice led to Harry and Meghan inviting them to their then new home at Windsor after they attended church on Easter Sunday.<\/p>\n They had tea and chatted for around 30 minutes at Frogmore Cottage <\/a>. At the time, a palace source told the Mirror<\/a> : \u201cThe Duchess and Harry have developed a very close bond over the years.<\/p>\n \u201cKate is acutely aware of the importance of William and Harry getting along, not just because of perception but their collective responsibility to the monarchy as a whole.”<\/p>\n Get the inside scoop on the monarchy with Mirror Royal<\/p>\n WHATSAPP GROUP: <\/strong>Be first to get the biggest royal bombshells and exclusives to your phone by joining our Royal WhatsApp here<\/a><\/strong>.<\/p>\n We also treat our community members to special offers, promotions, and adverts from us and our partners.
