Kate and William's third child,Queen Elizabeth's sixth great-grandchild, is fifth in line to the throne, after grandfather Prince Charles, father Prince William and the two older siblings.

A 2013 change to the law means that for the first time inBritish history, a new prince will not supplant his older sister in theorder of succession. Previously, younger males would takeprecedence over older female siblings.

William's younger brother Harry, who marries U.S. actressMeghan Markle next month, falls to sixth on the list.

Queen Elizabeth, Prince Charles, the baby's grandfather, andother members of the Royal Family and Kate's family have beeninformed and "are delighted with the news,"Kensington Palacesaid.

Highly anticipated name decision

William appeared outside the hospital just after 4 p.m. local time, waving to onlookers before departing by car and returning about 30 minutes later with George and Charlotte, who waved to the crowd.

The official announcement of the birth was made by placing anotice on an easel in the forecourt of the Queen's London home,Buckingham Palace, a tradition that has been in place since itbecame the sovereign's official residence in 1837.

Independent town crier Tony Appleton stands outside the Lindo wing of St Mary's hospital and announces the birth of the Duke and Duchess of Cambridge's third child, a boy.

Prime Minister Theresa Maycongratulated the Royal Family.

"My warmest congratulations to the Duke and Duchess of Cambridge on the birth of their baby boy," May said. "I wish them great happiness for the future."

Canadian Prime Minister Justin Trudeau and Gov. Gen. Julie Payette were among the international well-wishers.

The duchess carried out her last official engagement on March 22 before going on maternity leave.

As in her previous pregnancies, Kate suffered from hyperemesis gravidarum, a severe form of morning sickness. Officials announced both her previous pregnancies before the traditional 12-week mark because she was too unwell to attend public engagements.

The birth was being overseen by consultant obstetrician Dr. Guy Thorpe-Beeston and consultant gynecologist Dr. Alan Farthing who were also called in for the births of George and Charlotte as well as the hospital's midwives.

Like the baby's other siblings, hisfull title will be HisRoyal Highness, Prince, followed by several given names.Kensington Palace said the name of the new royal would be announced in due course.

Until a 2013 law change, the Succession to the Crown Act, the baby boy's gender would have seen him move ahead of Charlotte in succession.

William gave up his day job as an air ambulance pilot last year to concentrate full time on royal duties on behalf of his grandmother.

Television crews, journalists and royal fans had set up camp outside the hospital for the "royal baby watch" since early April.
