Britain's Prince William and his wife Kate have named their newborn son Louis Arthur Charles, who will be known as His Royal Highness Prince Louis of Cambridge, Kensington Palace said today.

The prince, who is fifth in line to the British throne, was born at 1001 GMT on April 23 weighing 8 lbs 7oz.

Louis is William's fourth name as well as being that of Earl Mountbatten, to whom William's father Prince Charles was particularly close. Mountbatten was the uncle of Prince Philip, 96, great-grandfather of the new prince.

Charles, heir to the throne, has said it was a great joy to have another grandchild.

William and Kate now have three children: Louis joins Charlotte, 2, and George, 4.
