Britannia Unchained: Global Lessons for Growth and Prosperity is a political book written by several British Conservative Party MPs and released on 13 September 2012.

Its authors present a treatise, arguing that Britain should adopt a different and radical approach to business and economics or risk "an inevitable slide into mediocrity".

[1] The book was written by Kwasi Kwarteng, Priti Patel, Dominic Raab, Chris Skidmore and Liz Truss, five Conservative MPs who were elected in May 2010 and belong to the party's Thatcherite-leaning Free Enterprise Group.

The text sets out their vision for the United Kingdom's future as a leading player in the global economy, arguing that Britain needs to adopt a far-reaching form of free market economics, with fewer employment laws and suggesting the United Kingdom should learn lessons from the business and economic practices of other countries, including Canada, Australia and the tiger economies of East Asia like Taiwan, Hong Kong and Singapore.

Whereas Indian children aspire to be doctors or businessmen, the British are more interested in football and pop music.It says the UK should "stop indulging in irrelevant debates about sharing the pie between manufacturing and services, the north and the south, women and men".

[7] The book caused controversy in August 2012 after a short quotation appeared in London's Evening Standard which accused British workers of laziness and lagging behind their Asian counterparts.

[9] The Labour Party urged British Prime Minister and Conservative leader David Cameron to distance himself from the views[10] and the Shadow Secretary of State for Business Chuka Umunna commented: "First they blame British businesses for their economic failures and now they blame the people who work within them, showing how out of touch the Tory party has become".
