The ONS has delayed to Jan 25 the upcoming Nov and Dec PPI releases which were due out on Jan 18. The Nov release had been cancelled due to various issues within detailed item prices, and the Oct data had large errors which required revision.

• The ONS investigations are now "complete" and they are finalising Nov and Dec PPI data along with an updated back series for release on Jan 25.
• Note that the Dec CPI data are unaffected and that release is still set for Jan 18.
