Kate and William say they are "extremely moved" by all the messages received since the announcement of the princess's cancer. Both are “extremely moved by the warmth and support from the public,” a Kensington Palace spokesperson told the BBC.

The couple have already announced that they will not attend Easter mass this year, a usually busy gathering time for the royal family. Their children George, Charlotte and Louis started their Easter school holidays on Friday and will return to school on April 17. Until then, the family should stay behind.
