(2) what the total liability of unfunded public service pension schemes was as at 31 March in each year since 1997.
Total unfunded public service liabilities are estimated to be £530 billion at 31 March 2005. The two previous comparable estimates of this total were £460 billion at 31 March 2004 and, and £425 billion at 31 March 2003. The estimates for years prior to 2003 were not made on a comparable basis. As noted in the 2007 pre-Budget report (Cm 7227), updated estimates of the unfunded public service liability will be published alongside the next long-term public finance report.
