Justine Greening was named the "MP of the Year" on Wednesday in recognition of her work with deprived and minority communities.
The education secretary won the honour following a blind-judging process, which looked at the work of MPs helping the underrepresented across the country.
Ms Greening, MP for Putney, said she felt honoured to win the award, set up by the Patchwork Foundation, a charity that aims to promote positive integration across the UK.
Praise from the PM
“The Patchwork Foundation does a fantastic job of getting young people involved in our democracy and political process, with its workshops and mentoring,” she said.
“That's all vital if we're going to have a political system that works for everyone and is inclusive. It’s been great to be involved as an MP and, locally, I do my best to work with our whole community on the issues that matter to all of us.”
The Cabinet member was congratulated by Prime Minister Theresa May, who said Ms Greening's award fitted with her own “driving mission in politics" to make Britain "a country that works for everyone – where you can rise to the top no matter who you are and where you are from”.
The award was announced by Speaker of the House of Commons, John Bercow, at the Speaker's House in Westminster.
