Kensington Palace says the Queen is delighted by the news from the Duke and Duchess of Cambridge

Prince William and Kate, the Duke and Duchess of Cambridge, are expecting their third child, Kensington Palace said today. 
The announcement comes as a surprise, as there had been little indication that William’s wife, the former Kate Middleton, was pregnant.

“The Queen and members of both families are delighted with the news,” the palace said in a statement.

“This is fantastic news,” British Prime Minister Theresa May said. “Many congratulations to the Duke and Duchess of Cambridge.”

William, 35, is the eldest son of Prince Charles, the first in line to the throne, and the grandson of the Queen and Prince Philip. 
The baby would be fifth in line to the British throne, after grandfather Prince Charles, father William and elder siblings George, 4, and Charlotte, 2. The baby’s arrival next year would push William’s younger brother Harry down to sixth in the line of succession.
Harry gave a thumbs up when he was asked Monday about the royal baby expected by his brother and sister-in-law as he arrived for a visit in Manchester, adding: “Fantastic. Great. Very, very happy for them.” 

As with her other two pregnancies, the duchess, also 35, is experiencing severe morning sickness (hyperemesis gravidarum), so cancelled her engagements Monday. 

No details were immediately available about when the third baby is due, but betting agencies were quick to start offering odds on possible names.

Paddy Power offered 8-to-1 odds on Alice if the baby is a girl. Also popular was Diana, after Prince William’s late mother, the Princess of Wales, particularly given the timing of the announcement. 

Together with Prince Harry, William and Kate have taken a leading role in marking the 20th anniversary of Diana’s death.

Last week, the royals toured the garden of their Kensington Palace home to remember the princes’ mother and celebrate her contributions to their family and the monarchy.

The royal couple are also due to mark a family milestone later this week: They are set to send George to school for the first time on Thursday.

From the time of their engagement, the royals have said that they wanted to have children — the only question was how many. Royal watchers recorded every aside for clues as to their plans.

When asked on a royal tour in Singapore in 2012 about how many children he wanted, William said he was “thinking about having two.”

More recently, during a royal tour of Poland, Kate joked about a third child when given a cuddly toy designed to soothe tiny babies.

Kate thanked the well-wisher for the present and turned to William. “We will just have to have more babies,” she joked.

The royal couple can also be seen as following in the footsteps of William and Harry’s grandparents, Queen Elizabeth and Prince Philip, who have four children.
