Labour leader Ed Miliband has declared his ambition to "rebuild Britain as One Nation", as he seeks to place his party firmly in the political centre ground.
The One Nation slogan was first used by Conservative prime minister Benjamin Disraeli in the 19th century and has long been linked with the political centre-right, and Mr Miliband made no bones about the fact that he was stealing it from the Tories.
David Cameron has lost the right to call himself a One Nation Prime Minister or claim that "we are all in this together" because of the way he has governed and his decision to hand tax cuts to millionaires while cutting services and benefits for the poor, he said.
Delivering his keynote speech without notes to Labour's annual conference, Mr Miliband explained how his upbringing as the child of Jewish refugees from Nazism and a comprehensive schoolboy in north London helped to form his political beliefs.
In deeply personal passages, the self-professed atheist described himself as a "person of faith", whose faith was not in a religion but in a shared value system which involves the duty to work together to make the country better and never to shrug his shoulders at injustice.
Mr Miliband said that Britain's One Nation spirit was shown in the Second World War, when people of all backgrounds worked together to defeat Hitler's Germany, and in the post-war era of Labour prime minister Clement Attlee, when they worked together to rebuild the battered country.
He stressed that he was not offering a return to the politics of Attlee or Disraeli, but calling upon the country to show the same spirit in rebuilding Britain's economic prosperity in the wake of the financial collapse and recession.
Britain has overcome its greatest challenges by coming together as one nation in the past, and can overcome the challenges of 2012 by doing the same now, he said.
He set out his proposals for a One Nation banking system, in which deposits left by ordinary savers in high street branches cannot be used in the "casino" activities of the same bank's trading arm; One Nation education, providing a "gold standard" vocational education with English and maths to 18 for children who are not going to university; and One Nation business, with reforms to takeover rules and shareholder rights to encourage long-term investment.
Aides said that Mr Miliband wrote the speech himself over the course of the past few weeks, and decided to deliver it without notes to achieve a more direct and authentic connection with his audience in the hall and at home watching on television.
