Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what the size of the state pension fund was in (a) 2010, (b) 2011, (c) 2012, (d) 2013, (e) 2014, (f) 2015, (g) 2016 and (h) 2017.

The National Insurance Fund (NIF) is used to pay for contributory benefits, including the State Pension. The NIF has no borrowing powers, so maintains a working balance of at least 16.6% of projected benefit expenditure to ensure that the NIF can deal with short term fluctuations. Information on the historical NIF receipts and balance is available in the National Insurance Fund Accounts at: https://www.gov.uk/government/publications/national-insurance-fund-accounts
