Carole Middleton has been described as a "mastermind" in her daughter Pippa's romance with fiancé, James Matthews.
Mrs Middleton, whose other daughter is the Duchess of Cambridge, is said to be thrilled that the couple are marrying after almost a decade of speculation surrounding their relationship.
One friend said Miss Middleton's mother confided several years ago that she hoped they would give it a serious go. "This is something she has hoped for for quite some time," said one associate. "She appears to be something of a mastermind in making this happen."
Mr Matthews, 40, a hedge fund manager, reportedly proposed after arranging a meeting with Mrs Middleton, undoubtedly seeking permission for her daughter's hand.
