During a Jubilee visit to Singapore with his wife the Duchess of Cambridge, Prince William has revealed he wants two children.
The Duke of Cambridge has spoken in the past about starting a family with Kate but had not commented on numbers.
His admission came during a visit to the Gardens by the Bay attraction in Singapore when the royal couple went on a walkabout.
Corine Ackermann, 17, who was with school friends from the Tanglin Trust British School, said: "Someone asked him how many children he would like to have, and he said he was thinking about having two."
During the walkabout local children who had been given the morning off school chanted "Will, you're brill, Kate, you're great," and waved Union flags and home-made banners.
The royal pair planted a pachira glabra variegata tree to mark their visit, and as they left the Duchess said: "It's amazing. I hope we can come back in a few years when it's fully grown."
