Sir Peter Lampl, founder and Chairman of the Sutton Trust and Chairman of the Education Endowment Foundation, said:

“This is a stark warning about the social mobility challenge facing Britain.

“As the vote in the United States and the Brexit vote showed both here and in the States whole sections of society have been left behind.

“We agree with the Social Mobility Commission’s report that we need urgent action to stop Britain’s social mobility problem getting even worse.”
