I found a declaration of Values from One Nation as follows: (2019) - the ones on Social Responsibility and Public Services of particular interest? It also gives a list of MP's at that time who were committed to it.

*The United Kingdom: we believe in the United Kingdom as the embodiment of our shared values and as a force for good in defending our values in the world: we are patriotic Conservatives who reject narrow nationalism.
*Active global leadership: we believe the UK must be a leader on the world stage through our aid, trade and security commitments to tackle global challenges as a global citizen, through a strong defence and soft power commitment.
*Life Chances: we believe that everyone in our country – whoever and wherever they are from – has an equal right to a fair chance in life, and that bold reforms to welfare & vocational skills are central to tackling social injustice and creating an opportunity society.
*Social Responsibility: we believe in a strong society, and a social contract between all of us as fellow citizens, supported in our tax and welfare system.
*Public Services: we believe in our public services, properly funded by a growing economy, as fundamental to the wellbeing of our nation, in a mixed economy of public, private and third sector providers.
*Localism: we believe in the importance of place and Conservatives supporting the local, civic and voluntary over the bureaucratic, statist and compulsory.
*Environmental Stewardship: we believe that we all have a responsibility to act as stewards of our local and global environment, for the next generation, and as a duty to show global leadership on climate change and biodiversity.
*Markets and values: we believe in free enterprise, business and the market economy with a framework of good regulation to enhance competition, support innovation, break monopolies, empower citizens and reflect our shared values.
*Law and Human rights: we believe in universal human rights and the rule of law and are proud of our country and Party's record in promoting them through an independent judiciary, effective enforcement, community policing & policies to prevent crime & social breakdown.
*Democratic renewal: we believe that civilised, open respectful political debate in our Party, Parliament & free press, and a vibrant arts & cultural sector, is fundamental to strengthening the health of our society and democracy.
