Cardinal Vincent Nichols, Archbishop of Westminster, said on Tuesday that he was “delighted” at the announcement that the Duchess of Cambridge is pregnant again. The news of Catherine’s second pregnancy was released in advance of her canceling a public engagement at Oxford University with Prince William. Catherine suffers from Hyperemesis gravidarum, extremely severe morning sickness in the early weeks of pregnancy, which can cause dehydration, weight loss and a build up of toxins in the blood and urine. During her first pregnancy with Prince George, Catherine was admitted to King Edward VII hospital. This time she is being treated at Kensington Palace by the surgeon gynaecologist to the Queen. Cardinal Nichols said: “I am delighted at the happy news that the Duke and Duchess of Cambridge are expecting a second child. Our prayers are with the family, and indeed all families awaiting the birth of a child.” Speaking yesterday, Prince William said: "(Catherine's) feeling OK, it's been a tricky few days... we're immensely thrilled, it's great news."
