The relevant figure can be found in the \"Consumer price inflation rates\" table under the column labeled \"CPI 12-month rate (%)\" for the relevant month.\n\nNote: the resolution source for this market will be the official monthly ONS CPI news release which reports inflation change over 12-month periods to only one decimal point (e.g. 1.9%).
