The arrival of Prince William, Duke of Cambridge, and his wife Catherine's first child will contribute more than £ 250 million to national economy. According to the estimates of Center for Retail in Nottingham, the baby gift items, books, toys and DVDs to sell as well as the cost of celebrations to be held throughout the country after baby's birth will contribute more than £ 250 million to national economy. The press has been waiting in front of St. Mary Hospital in the country while the gender of the baby is a curiosity among the bookmakers. The country has bet on the couple's first child's name which includes the names Diana, Elizabeth, Victoria, Charlotte, Alexandra, George, James, Philip, Charles, Richard. The public announcement of the royal baby birth is expected to be made according to the decades-long tradition. Accordingly, the sex and the weight of baby will be written on a paper which has Buckingham Palace emblem on. Royal officials will give the paper to a car in front of the hospital where many press members will be waiting and the paper will be sent to Buckingham Palace. Under past rules, a girl born to William and Kate would have been styled Lady and not known as Her Royal Highness, only a first-born boy would automatically become a Prince. But the Queen has taken action by issuing a new Letters Patent to ensure that her future great-granddaughter title will be Princess. Kate and William married on April 29, 2011 at Westminster Abbey with a magnificent wedding.
