Kate Middleton suffers another bout of morning sickness and Prince William pulls out British Military Tournament

Prince William has pulled out of attending the British Military Tournament tonight so he can spend time with wife Kate Middleton, who is recuperating after spending three nights in hospital.

The royal couple had both originally been due to attend tonight’s event but all of Kate Middleton’s forthcoming public engagements were cancelled after she received treatment for severe morning sickness.

It comes after Prince William, 30, joked at an event yesterday evening that morning sickness should be renamed as Kate Middleton suffered it all day and night.

It now appears unlikely that the Duchess will attend the premiere of The Hobbit: An Unexpected Journey film in the West End on Wednesday, and may not make another public appearance for several weeks.

A St James’s Palace spokesman said: “The Duke of Cambridge will no longer attend the British Military Tournament at Earl’s Court this evening, but will spend Sunday privately with the Duchess instead.

“It is well known that hyperemesis gravidarum often recurs and, until further notice, to allow the Duchess a degree of privacy during her pregnancy, we do not intend to offer regular condition checks or advise of routine developments associated with it.”

The cancellation of Prince William’s attendance at the event, billed as “the largest display of military theatre in the world”, comes after he last night attended a charity event.

He went solo for the first time since the pregnant Duchess of Cambridge, also 30, was discharged from hospital.

The Duke of Cambridge attended a glittering charity tennis gala, the Winter Whites Gala, held in aid of homeless charity Centrepoint, at the Royal Albert Hall in London.

He was due to be accompanied by the Duchess, but she is resting after suffering from hyperemesis gravidarum, an acute – and potentially dangerous – form of morning sickness.

Prince William, who is patron of Centrepoint, was congratulated by many on the news that a baby is on the way.
