Mo Gilligan, Saffron Barker, Stephen Mulhern, Bear Grylls, Hannah Cockroft, and Millie Bright are backing Make-A-Wish UK's latest campaign for World Wish Day 2021, after research shows the number of children in the UK who are eligible for a wish has doubled in the last 15 years.

The campaign 'celebrates the hope that a wish brings to a child living with a critical illness', and the charity posted on Instagram 'You have the power to create magical moments like this for more children. This #WorldWishDay don’t wait for hope, create it'.
