From The Purple Book To Lord Glasman's Blue: The Changing Colours Of The Labour Party

In response to Chancellor George Osborne’s recent Autumn Statement, the Labour Party was deeply critical of the economic policies of the coalition, its swathing spending cuts leading to little increase in the country's prosperity.

The readjustments made by the coalition and the Office for Budget Responsibility to its predictions for the future of the British economy include public spending cuts until 2016 and 2017. Therefore, the economy and the recovery from a potential second recession will almost certainly be at the forefront of the every party’s manifesto come the next General Election.
