Queen Elizabeth, Prince Philip to miss Prince Louis' christening

Queen Elizabeth and Prince Philip will miss Prince Louis’ christening at St. James’s Palace in London, Kensington Palace announced Monday.

The queen and the Duke of Edinburgh made the decision not to attend Monday's event “some time ago” and the reason was not health-related, the palace added.

Kate Middleton gave birth to her third child with Prince William in April, putting Prince Louis fifth in line for the British throne. The couple selected six of their friends — Nicholas van Cutsem, Guy Pelly, Harry Aubrey-Fletcher, Lady Laura Meade, Mrs Robert Carter and Lucy Middleton — to be Louis’ godparents.

The 11-week-old’s christening is expected to be a small event with immediate family and godparents, Sky News reported.
