The Orange Book

The Orange Book: Reclaiming Liberalism is a book written by a group of prominent British Liberal Democrat politicians and edited by David Laws and Paul Marshall in 2004. Three contributors later became leaders of the Liberal Democrats: Nick Clegg, Vince Cable and Ed Davey. Other contributors include Chris Huhne, Susan Kramer, Mark Oaten and Steve Webb. The book's central philosophy, and some of its ideas, are supported by Liberal Reform, an internal group of the Liberal Democrats. It has been compared with The Purple Book: A Progressive Future For Labour, published seven years later by senior members of the UK's Labour Party, who were associated with the governments of Tony Blair and Gordon Brown.

The term Orange Bookers refers to those in the party who subscribe to the book's emphasis on greater personal choice and possible market solutions.

In the book, the group offers liberal solutions—often stressing the role of choice and competition—to several societal issues such as public healthcare, pensions, environment, globalization, social and agricultural policy, local government, the European Union and prisons. It is usually seen as the most economically liberal publication that the Liberal Democrats have produced in recent times.
