Britain's Duchess Catherine's parents "offer the closest to ordinary life" for the newborn princess.

The 33-year-old royal delivered her second child with Prince William yesterday morning (02.05.15), and royal experts believe it is the tot's maternal grandparents Michael and Carole Middleton who will provide a degree of normality to her life away from the spotlight.
Royal writer Robert Lacey explained: "The thing about the Middletons is that they are thoroughly self-assured and self-contained. They have a stable home and family life, and that clearly appeals to William.
"Even when he goes down to stay with his grandparents in the country, Prince George is surrounded by security.
"It's difficult to say it's an ordinary life but perhaps the Middletons offer the closest to ordinary life inside that stockade of security."
The as-yet unnamed Princess of Cambridge was born at 08.34am BST weighing 8lbs 3oz, and despite only being a day old, experts have already predicted she will have a huge impact on the British economy, with the potential to raise £150 million for businesses and designers in the UK every year of her life.
Brand expert Robert Haigh told the Sunday Mirror newspaper: "This baby girl opens up a whole new demographic for the 'Brand Windsor-effect'.
"In the years to come her wardrobe will be carefully scrutinised, with the specific items she wears likely to sell out in days and the labels enjoying long-lasting uplifts in brand strength and sales."
