Boris Johnson’s Conservative party went into the general election campaign with an 11-point lead over Labour, according to the FT’s poll of polls. The gap has since widened slightly.
The poll tracker combines all voting intention surveys published by major British pollsters. The trend line uses only the most recent poll from each pollster and weights them according to when they were conducted.
We will update this page with additional polls as their data tables become available.
How it works
The FT poll-of-polls tracks voting intention polls covering England, Scotland and Wales combined, and calculates a rolling average for each party.
At each moment in time, the FT poll average is calculated using only the most recent poll from each pollster. This ensures that data from pollsters that conduct polls more frequently than others does not have a disproportionate impact.
Individual polls are also weighted to give prevalence to more recent data. The weighting diminishes over time so that a poll no longer has any effect on the trend line after 30 days.
The resulting live-updating chart displays the individual polls as dots and the trend as a line.
