The Duke and Duchess of Cambridge

Britain's Duke and Duchess of Cambridge's parenting is expected to mirror Princess Diana's.

The royal couple - who are expecting their first baby this month - should learn from Prince William's mother and attempt to give their child a relatively normal upbringing, according to Princess Margaret's official biographer Christopher Warwick.

He explained the huge impact Diana's parenting had on the British prince and it is expected the couple will raise their child in a similarly low-key way.

He said: "William and Harry were very, very fortunate with Diana as a mother because her ideas were so different to the previous generation.

"The importance of this to her two sons have been enormous. William will want this for his children."

Diana - who died in a car crash in 1997 - was a hands-on mother and her son will look to continue her tradition while Kate will want her child to have the same "ordinary" upbringing she enjoyed.

Christopher added: "Her childhood was pretty ordinary. She won't want her baby to be the subject of rules and protocol before they need to be."
