Opinion polling for the 2017 United Kingdom general election

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by Mélencron (talk | contribs) at 01:09, 25 February 2017 (I'm not trying to "make a point".

In the run up to the next United Kingdom general election, various organisations are expected to carry out opinion polling to gauge voting intention. Results of such polls are displayed in this article. Most of the polling companies listed are members of the British Polling Council (BPC) and abide by its disclosure rules.

The date range for these opinion polls is from after the previous general election, held on 7 May 2015, to the present day. Under fixed-term legislation, the next general election is scheduled to be held on 7 May 2020.

Most opinion polls cover only Great Britain.

Most YouGov polls include the Scottish National Party and Plaid Cymru as single options.

Poll results

Poll results are listed in the table below in reverse chronological order.[1] The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. The "Lead" column shows the percentage-point difference between the two parties with the highest figures. In the instance of a tie, no figure is shaded but both are displayed in bold. Poll results are generally rounded to the nearest percentage point (where a result is less than 0.5%, but more than zero, it is indicated by '*').

The six parties with the largest numbers of votes in the 2015 general election are listed here. Other parties are listed in the "Other" column.

  Conservative Party (Con)
  Labour Party (Lab)
  UK Independence Party (UKIP)
  Liberal Democrats (Lib Dem)
  Scottish National Party (SNP)
  Green parties (Green Party of England and Wales and Scottish Green Party) (Green)

Preferred Prime Minister polling

Some opinion pollsters have asked voters which party leader they would prefer as Prime Minister – Theresa May (Conservative Party) or Jeremy Corbyn (Labour Party). Most pollsters also include 'Not Sure' as an option, while others also provide 'None of these' as an option. Polls published prior to Theresa May’s election as Conservative Party Leader offered then-Prime Minister David Cameron as the Conservative option.
