A theory on when and where Prince Harry and Prince William will meet PLUS Piers Morgan calls teh kettle black -

The Express noticed Harry is set to speak at the Invictus Games 10th Anniversary Service to be held at St. Paul’s Cathedral on May 8.
A copy of the official St. Paul’s Cathedral schedule shows the Invictus Games event listed as taking place on Wednesday, May 8 at 5 pm.
The Express further reports both Prince Harry and Meghan Markle are listed as guests on the official running order and the Duke of Sussex is set to speak at the service. Get your popcorn ready.

Another potential for a reunion between the brothers wil come in May.
With invitations dispatched for Duke of Westminster Hugh Grosvenor's wedding, a society guessing game has developed as to whether  Harry will attend the event in June..

Sources report that Grosvenor, is staying neutral, maintaining a good relationship with both brothers, leaving it up to them to resolve their family drama. However, the home team could have an advantage as the Duke is godfather to Prince George, who could be a page boy on the big day in Chester Cathedral.  And think about it, if you could have the future king in your wedding wouldn’t you, just for the bragging rights?

Royal insider Deep Crown weighed in on the situation, saying, "The Duke of Westminster's wedding presents a unique opportunity for the estranged brothers to come together and put aside their differences, if only for a day. The fact that Prince George, the Duke's godson, may play a role in the ceremony adds an extra layer of significance to the occasion."

 "While it is ultimately up to the princes to decide whether they will attend and how they will interact, the Duke's neutrality and the familial ties between the Grosvenors and the royal family could create a space for reconciliation. It remains to be seen whether Prince Harry will choose to attend in person or perhaps via video, as he did for the recent Diana Legacy Awards."
