Prince William will be replacing his wife the Duchess of Cambridge for the visit to Malta this weekend, the Kensignton Palace website said this morning.
Kate Middleton was scheduled to visit Malta on Saturday and Sunday as part of celebrations for Malta's 50th anniversary of Independence, but she is suffering from morning sickness. She is pregnant with the royal couple's second child.
The news has also been confirmed by the government of Malta. The Duchess of Cambridge is still suffering from Hyperemesis Gravidarum.
The decision that it will be the duke, not the duchess, who will come to Malta was taken by the royal couple on the advice of doctors.
The government said that the programme of activities will remain the same as planned.
