Duchess Catherine is against Prince Harry’s relationship

Britain’s Duchess Catherine doesn’t want Prince Harry to marry Cressida Bonas.

The Duchess of Cambridge is reportedly less than enthusiastic about the idea of the 28-year-old royal tying the knot with his free-spirited girlfriend because Cressida’s half-sister Isabella Calthorpe was the reason she and Prince William briefly split up in 2007.

A source told the Daily Telegraph newspaper: “Cressida has said Kate is not keen on her relationship with Harry. Cressie and Isabella could not be closer. Where she goes, Bella goes.

“Kate does not like Isabella because William loved her, and that caused their break-up. Bella’s treatment at the royal wedding won’t be forgotten.”

Isabella – who married Sir Richard Branson’s son Sam earlier this year – was invited to the nuptials of the Duke and Duchess of Cambridge in 2011, but was not allowed to involved in either of the two receptions that followed the ceremony.

William called time on his relationship with Duchess Catherine – who was known as Kate Middleton before the tied the knot – six years ago after he fell for Isabella but following her rejection of his declaration of love, he returned to Kate.
