Catherine, Duchess of Cambridge London - Arab Today Catherine, Duchess of Cambridge and husband Prince William on Monday welcomed their first child, a baby boy, after weeks of anticipation among fans of the royal family over the arrival of a new heir to the British throne. The baby was born at 4:24 p.m. London time, weighing 8 pounds, 6 ounces. A name has not yet been announced for the child, who is now third in line to the throne. The newborn is Queen Elizabeth II’s third great-grandchild. Following tradition, the public announcement of the House of Windsor’s newest arrival was withheld until the queen and senior members of the royal family were notified. Afterwards it was posted both on paper on an easel at Buckingham Palace and on social media networks worldwide.
