Daughter to Duke and Duchess of Cambridge 'should be given title Princess of Wales' "I think it sends out a positive message that the people of Wales have a direct representative and we're fully locked into the monarchical system of government and I think it's symbolic because the role of Prince of Wales does not automatically bestow any rights or privileges or responsibilities but as a powerful symbol, really, that Wales is an integral part of the United Kingdom," Mr David said. A Cabinet Office spokesman said it will be a matter for the Palace to decide. This comes after Nick Clegg urged 'equal rights' for royal girls, stating that Parliament must change Britain's "arcane" rules of succession to ensure a first-born daughter of the Duke of Cambridge would be Queen. The deputy Prime Minister said the current rules are "out of date" as he urged MPs to back changes to the law during the House of Commons debate today. Introducing the reforms for the Government, Mr Clegg will say they "couldn't be more timely" as the Duke and Duchess of Cambridge are expecting their first child. "The other Commonwealth countries where Her Majesty The Queen is head of state have just given us the green light to change the law, and we are wasting no time," Mr Clegg said last night. At the moment, if the first child of the Duke and Duchess of Cambridge is a girl, any younger brothers she has will overtake her in line to the throne. We're modernising these out of date rules so that men and women in line to the throne have equal rights. He said the law must also be changed to allow royal heirs the right to marry whoever they like and keep their entitlement to the throne. "The current law also says that our monarch can't be married to a Catholic," he said. This legal ban doesn't apply to any other faith - not Muslims, Jews, Hindus, nor to atheists. Just Roman Catholics. The reasons for this go back 300 years, to the days when Britain was worried about the threat from its Catholics neighbours, such as Louis XIV of France. Times have changed, along with our attitudes towards each other. It is time for us to bring these arcane laws up to date. MPs are expected to be generally supportive of the Bill, but the Lords Constitution Committee has warned more debate is needed to uncover potential problems that may have been "overlooked or hidden." There also have been reports that Prince Charles and senior figures within the Church of England are concerned about the "unintended consequences" of rushing through new rules. Lord Carey, the former Archbishop of Canterbury, has suggested removing the ban on a monarch marrying a Roman Catholic could upset a "delicate constitutional balance." However, the Church of England has written to MPs expressing its official backing for both the changes. A briefing from the Church said the ban on royal heirs marrying Roman Catholics is "not necessary to support the requirement that the sovereign join in communion with the Church of England." "Its proposed removal is a welcome symbolic and practical measure consistent with respect for the principle of religious liberty," the Church said. It reflects the sea change in ecumenical relations over recent decades.
