The Princess stepped out in a tuxedo suit and a very afforable bodysuit for her meeting. She also accessorised with a pair of pearl earrings.

Kate told the group: "Today I just want to think about and discuss what next, really. How do we keep this conversation going?

"This campaign's really to try and raise the awareness of the importance of this issue. And it's sort of what can we do collectively to keep the conversation going and what we do next.

"This campaign is really laying the foundation of why early childhood matters."

The royal mum-of-three said it is about what helps shapes us, what shapes our relationships, and the emotional experience of childhood and about creating the "building blocks and the scaffolding" for how we first start to understand ourselves and others.

"These are really complicated, big issues to look at," she said. "But I think, from the centre's point of view, one of the main key areas is how do we develop the social and emotional skills which are vital for later life. How do we better manage and regulate our emotions? How do we build better relationships?"

She said they are dealing with "big questions, big topics" which are "complicated".

The centre stems from research which shows that the first five years of childhood fundamentally shape adulthood, with social challenges such as addiction, violence, family breakdown, homelessness and mental health having their roots in the earliest years of life.
