The Duchess of Cambridge's pregnancy sickness will almost certainly force her to miss Wednesday's UK premiere of The Hobbit, a health charity has said.

Kate and William are guests of honour at the screening of the latest blockbuster from director Peter Jackson, who brought the Lord of the Rings trilogy to the big screen.

St James's Palace has said a decision on whether Kate would attend the Odeon at Leicester Square would be made nearer the time.
