Prince Harry and Meghan Markle had dinner with Prince William and Princess Kate after they received the Queen’s coffin at Buckingham Palace.

The foursome joined other royals on Tuesday as Her Majesty spent a final night at her London residence.

Harry and Meghan had earlier stood behind King Charles and Queen Consort Camilla on the steps of the grand entrance of the Palace.

The Queen’s coffin was then driven past thousands of mourners through the gates in a hearse she helped design.

It is understood the family affair was a small and private gathering with no pictures released.

But it has emerged there was an intimate dinner attended by the two brothers in another sign they are willing to put their tense relationship aside to mourn the Queen, The Sun reported.

Harry and William have come to a truce as they unite together in grief.

They made a surprise appearance together with their wives to view flowers at Windsor on Saturday.

Before the display of unity, the brothers had barely spoken to each other after Harry left the royals for a life in the US.

They were last seen together in public at the Queen’s Platinum Jubilee celebrations in June.

The new-found reconciliation continued yesterday when the brothers walked together on the Queen’s sombre procession to Westminster Hall.

William and Harry looked emotional as they stood side-by-side while following the coffin in a haunting reminder of their mother Princess Diana’s funeral in 1997.

They were later pictured in a group of four with Meghan and Kate as they joined prayers in a poignant service for Her Majesty.
