Duchess to miss Invictus Games opening due to morning sickness

The Duchess of Cambridge, who is suffering from acute morning sickness, will not attend the Invictus Games opening ceremony this evening or the athletics event tomorrow, Kensington Palace said.

Kate, who is expecting her second child, was also forced to cancel an engagement in Oxford earlier this week.

Meanwhile, David Beckham has given some friendly advice to the Duke and Duchess of Cambridge ahead of their new arrival - get some more sleep.

"With the commitments that they have to be a great mum and dad is pretty incredible," Beckham said.

There is already speculation that the royal couple's second child could be due in April.

Royals 'miss privacy' due to early baby announcement

Royal historian Dr Kate Williams has said that it must be "very hard for William and Kate" after they were forced to announce the Duchess' pregnancy early, meaning "they don't have that early period of privacy".

As with her last pregnancy the Duchess of Cambridge has suffered from hyperemesis gravidarum (severe morning sickness).

This has meant she has been prevented from carrying on her royal duties, forcing the palace to confirm both pregnancies earlier than most parents might go public.

Expectant parents usually wait until after the first trimester.
