She said: “The Queen is all about forgiveness – look at Fergie and Andrew – and she would certainly be happy to have Harry and Meghan around her for the Platinum Jubilee celebrations.
“Their meeting at Windsor on Thursday shows the olive branch has been offered to them and she will be hoping they accept it.
“She wants to present a united family on an occasion like the Jubilee, because an occasion like that certainly won’t happen again.”

Following their decision to step down as senior royals in early 2020, relations with the Firm were said to have been strained after the Duke and Duchess of Sussex’s controversial interview with Oprah Winfrey.
The Duke has expressed doubts about his family’s safety in the UK after the government withdrew his taxpayer-funded security.
He is seeking a judicial review of the decision, which is one of the reasons he gave for not attending the Duke of Edinburgh’s memorial service last month.
However, the heavy security surrounding a royal showpiece event like the Jubilee may persuade the Sussexes to attend.

The Duke accused his father of failing to support him and cutting him off financially.
However, palace sources told the Telegraph that the meeting was not a “summit” designed to repair relationships, describing it instead as a normal family meeting between father and son.
