Featuring a lion cub and unicorn inspired by the Royal Arms, the Royal Collection china is decorated with gold ribbons, silver pompoms and a coronet-inspired pattern.

The pieces bear the words 'Welcome to our new royal baby', and display William and Kate's coronet.

The duke and duchess's baby son - their third child - arrived on Monday, weighing 8lb 7oz, and the prince of Cambridge made his public debut on the steps of the Lindo Wing, wrapped in a white blanket.

The official range includes a pillbox costing £35, a tankard for £39 and a plate priced at £49.

Each item in the range is gilded with 22-carat gold and made in Stoke-on-Trent using traditional methods.

There is also a pram-shaped woven decoration, made with glistening threads, delicate pearl detail, and embroidered on the back with 'Royal Baby 2018', for £14.95.
