In September 2019 we introduced improvements to the estimation of capital stocks. Recent quality assurance work has identified that although these improvements were fully implemented in the Public sector finances borrowing by sub-sector publication, they were not fully reflected in our presentation of public sector current budget and net investment as a ratio of GDP (series JW2V and MUB2 respectively), for the period - financial year ending March 1987 to the financial year ending March 1997. We have now updated these data in our time series dataset.
These updates have had no impact on our previous estimates of public sector net borrowing, cash requirement or debt. We apologise for any inconvenience.
