In this pre-debate, pre-manifesto stage of the campaign, my latest round of polling finds no signs of a seismic shift in opinion so far. We find a similar picture to last week’s, including a clear lead for Boris Johnson over Jeremy Corbyn as best Prime Minister and, in a forced choice, an overall preference for a Johnson-led Tory government over a Corbyn-led Labour one. Leave voters, however, appear more settled in their voting decisions at this stage than remainers. There are some small changes, but most are well within the margin of error.

When we ask people how likely they are to vote for each party on a 100-point scale, we find the Conservatives’ mean score up slightly since last week from 33 to 36, with the other parties unchanged: Labour on 25, the Liberal Democrats on 17, and the Brexit Party (asked only of voters in non-Conservative seats) on a mean score of 11.

2017 Conservative remainers’ average likelihood of voting Tory again rose slightly from 57 to 61, and Conservative Leavers’ from 77 to 82 (in non-Tory seats, their declared chance of voting for the Brexit Party was 24/100). Overall, 2017 Tories’ likelihood of sticking with the party rose from 72 to 76. Labour leavers’ likelihood of voting Conservative rose slightly from 24 to 28, but stayed behind their likelihood of staying with Labour (down from 38 to 36/100). Overall, 2017 Labour voters put their chance of supporting the party again at 55/100, down from 57 last week.

Leave voters’ mean likelihood of voting Conservative is 61, with the Brexit Party (in non-Tory seats) on 24, and Labour on 11. Remain voters’ average likelihood of voting Labour is 40/100, ahead of the Lib Dems on 31, the Conservatives on 18 and the Greens on 16. The Lib Dems’ highest likelihood scores, apart from their 2017 voters, come from those who say they want to remain in the EU but with a Prime Minister other than Jeremy Corbyn.

In Scotland, voters’ mean self-declared likelihood of voting SNP is 34/100, with the Conservatives on 22, Labour 18, the Lib Dems on 15, the Greens on 10 and the Brexit Party on 9.

Boris Johnson’s lead over Jeremy Corbyn as “best Prime Minister” remains steady at 20 points, compared to 19 points last week. The proportion of 2017 Conservative remainers naming Johnson is up from 65 per cent to 71 per cent, but among Labour leavers it is down four points at 40 per cent, with a corresponding increase in “don’t knows” – still only 23 per cent of them say they think Corbyn would be better. Those who say their ideal outcome would be to leave the EU but with a Prime Minister other than Johnson nevertheless say he is the best choice of the two PMs on offer, by 41 per cent to 17 per cent with 42 per cent saying they don’t know).

When we forced people to choose between a Conservative government led by Boris Johnson or a Corbyn-led Labour administration, Johnson and the Tories came out ahead by 12 points (56 per cent to 44 per cent), down from 14 points last week, but with only a one-point move at either end. Among 2017 Labour leavers, the preference for Johnson and the Tories was down from eight points to four. People who ideally wanted Brexit without Boris still preferred a Johnson-led Conservative administration to Labour and Corbyn by 64 per cent to 36 per cent.

The proportion saying Jeremy Corbyn as Prime Minister would be worse for Britain than leaving the EU is unchanged at 49 per cent, with 38 per cent taking the opposite view. The proportion of both Conservative and Labour remainers saying Corbyn would be worse is fractionally up on last week, but the number of Labour leavers taking this view is down slightly from 58 per cent to 52 per cent.

Asked for their ideal combination of Prime Minister and Brexit outcome, 35 per cent said they wanted to leave the EU and have Boris Johnson as Prime Minister; a further 10 per cent said they would like to leave but with a Prime Minister other than Johnson. Only 18 per cent said they would like to remain and have Jeremy Corbyn as Prime Minister, while one in four said they wanted to remain but with a Prime Minister other than Corbyn.

In other words, while most of those who want to leave are happy to have Johnson in Number Ten, most of those who want to remain don’t want the Prime Minister who would make that possible. Nearly half of all Remain voters, including 41 per cent of 2017 Labour remainers, said they would like to remain in the EU with a Prime Minister other than Corbyn. Labour leavers were more evenly divided than most: 35 per cent wanted Brexit with Johnson, with 25 per cen wanting to leave with a different Prime Minister.

Both groups whose Brexit preference clashed with their Prime Ministerial one said EU policy was more important to them. Among those who wanted Brexit but with a Prime Minister other than Johnson, more than two thirds (68 per cent) said that if they had to choose, they would leave the EU and put up with Johnson in Downing Street. Exactly the same proportion of those who wanted to remain but without Corbyn said they would put up with him in Number Ten to stop Brexit.

As last week, the most frequent answer when we asked what specific election stories people had noticed in the past few days was “none”. Notably, public spending promises, Labour’s free broadband policy, floods and the NHS were all mentioned more often than Brexit.

Twice as many people expect Boris Johnson to win tonight’s ITV debate as think Jeremy Corbyn will come out on top. 36 per cent think Johnson will win (including 21 per cent who think he will do so “easily”), while the 18 per cent who name Corbyn are equally divided between thinking he will win easily and that “it will be close.” Nearly one in five think “there will be nothing to choose between them,” and nearly three in ten say they don’t know who they expect to do best

Just under half (47 per cent) of respondents said they had definitely decided how they would vote on 12 December. Those leaning towards the Conservatives were the most likely to say they had decided (68 per cent), with only just over half (54 per cent) of Labour leaners and only 37 per cent of those most inclined to the Lib Dems saying they had made up their minds. Seven in ten 2017 Conservative leavers said they had definitely decided, compared to just 48 per cent of Tory remainers. Labour remainers were slightly more likely to say they had finally decided (46 per cent) than Labour leavers (42 per cent).

More than half (56 per cent) of voters expect the Conservatives to have the most MPs after the election, though most of these think this will be within a hung parliament – only 22 per cent say they expect a Tory overall majority. Those leaning towards the Conservatives are the most likely to expect an outright victory, but fewer than half of them (47 per cent) do so. Only just over one in ten expect Labour to come out on top, either as the largest party in a hung parliament (eight per cent) or with an overall majority (three per cent).

Most voters (53 per cent) expect Boris Johnson still to be Prime Minister after the election, including 86 per cent of those currently leaning towards the Conservatives. Those saying they are most likely to vote Labour are evenly divided between expecting Prime Minister Johnson (32 per cent), Prime Minister Corbyn (32 per cent) and saying they don’t know who will be in Downing Street in 23 days’ time (35% per cent).

Our map of the campaign shows how different issues, attributes, personalities and opinions interact with one another. The closer the plot points are to each other the more closely related they are. This week we see, for example, that those in Conservative territory are most likely to have decided how to vote, while those who are less sure are more likely to be in the remain/Lib Dem part of the map. It is also notable that the most likely Brexit Party voters have moved: this week we only offered the party as an option to those in non-Conservative seats, and have found that having been close to likely Tory voters last week, it is now found closer to 2017 UKIP territory.
