2010-11: the Hutton review
On 20 June 2010, the Chancellor announced a fundamental review of public service pensions. John Hutton chaired the independent Public Service Pensions Commission, which produced an interim report in September 2010 and a final report in March 2011.
"The commission will make recommendations on how public service pensions can be made sustainable and affordable in the long-term, fair to both the public service workforce and the taxpayer, and ensure that they are consistent with the fiscal challenges ahead."
