- It includes polls up to and including 1 May.
- The last Poll of Polls had a 0.2% Labour lead and this week it is a 0.5% Conservative lead. Over the past five weeks of the main camapign Labour have always had a small lead, so this switch in lead could be significant. The switch is primary down to a number of polls with large(ish) leads for the Conservatives. Whether or not these are just outliers will be better know with next week”s polls – and also the only poll that matters.
