1. Main Prediction

The Conservatives have continued to gain ground under Boris Johnson, with the new Brexit deal also helping them to gain support.

Prediction based on a poll-of-polls, using six polls (Opinium, ComRes, Panelbase, Survation, Deltapoll, YouGov) from 15-Oct-2019 to 21-Oct-2019, sampling 9,790 people.

This has the Conservatives around 10pc ahead of Labour with a predicted majority of 82 seats.

Along with polling uncertainty, two factors could change this result significantly. If there is strong 'ABC' (anyone but the Conservatives) tactical voting, then the result could be much closer and the Conservative majority could be wiped out. On the other hand, if there were a pre-election pact between the Conservatives and the Brexit party then the Conservative/Brexit alliance could have a majority of 200 seats or more.

2. Brexit Deal — public attitudes

There has been some polling on public attitudes to the new Brexit deal.

2.1 New Deal

Asked whether they support or oppose the new Brexit deal (or think MPs should support or oppose it), the public shows mild to moderate support for the new deal, albeit with a considerable number of undecideds.

2.2 Another Referendum

Asked whether they support or oppose having a new referendum offering a choice between the new Brexit deal and Remain, the public has a slight bias against, but it is fairly close.

2.3 Referendum Result

Assuming there would be a referendum offering people the choice between the new Brexit deal and Remain, how would they vote. We only have data from two pollsters, which suggests that it is fairly close, but more people who have made up their minds would choose to vote for the deal.
