The tables below show the average of all UK Parliament polls in a given month.
Monthly polling averages, 2015-2021
Monthly polling averages, 2010-2015
Editor’s note: to ensure compatability, polls that covered the whole of the UK (including Northern Ireland) have had their Northern Irish respondents removed to give results for Great Britain (GB) only. Thus all results in this table are Great Britain (England, Wales and Scotland)-only.
