The event will be broadcast on Christmas Eve on ITV1 as part of the special programme Royal Carols: Together At Christmas, featuring additional material including films emphasising the importance of early childhood and contributions from celebrities like Rio and Kate Ferdinand and Dame Sheila Hancock.

Ahead of this, a video message from the Princess of Wales will be aired, in which Kate thanks those helping to ‘shape a happier, healthier, fairer world in the future’.

She will say: ‘Christmas is a time when we come together and celebrate the birth of a newborn baby.

‘The arrival of every baby is a precious and momentous time, it brings us together to reflect on new beginnings and brings hope for the future.

‘Throughout our earliest interactions, relationships and experiences, with those who love us, even before we are born, we lay the foundations to so much of what that future will depend on.

‘But only by valuing and supporting the vital role of the adults in a child’s world can we hope to make a difference.

‘And so tonight’s guests have been invited in recognition of their support of our youngest children, as we shine a spotlight on the critical role they play in nurturing and raising the future generation.

‘From parents and carers, to early educators, midwives, health visitors and community volunteers, thank you for all you do in helping the very youngest members of our communities, feel safe, valued and loved.

‘This is not just making a difference to children today, it will go on to shape a happier, healthier, fairer world in the future.’

The highlight of the show was a poignant musical tribute paid to George Michael and John Lennon – with the concert held 43 years to the day the former Beatle was shot dead.
