The Cornerstone Group supports the unitary governance of the British state and opposes attempts to transfer power away from it — either downwards through regionalism and devolution, or upwards to the international control of the European Union.

A manifesto released at the time of its foundation set out the Group's intentions:[2] We believe that these values must be stressed: tradition; nation; family; religious ethics; free enterprise.

To this end, it emphasises England's Anglican heritage, opposes any transfer of power away from the central government and institutions of the United Kingdom — either downwards to the nations and regions or upwards to the European Union — and seeks to place greater emphasis on traditional family structures to repair what has been termed as Britain's broken society, as well as calling for lower levels of immigration into the UK.

[citation needed] Its core focus points according to its website include the "monarchy; traditional marriage; family and community duties; proper pride in the United Kingdom's distinctive qualities; quality of life over soulless utility; social responsibility over personal selfishness; social justice as civic duty, not state dependency; compassion for those in need; reducing government waste; lower taxation and deregulation; and promotion and protection of ancient liberties against politically correct censorship and a commitment to the democratically elected UK parliament.

Though the group is marked out by its support for the Anglican Church, it also includes more traditional Catholic members such as Jacob Rees-Mogg and Edward Leigh.
