MRP Poll September 2026

24 September 2026

On behalf of Restore Britain, Electoral Calculus has conducted a new MRP poll. Polling using MRP, which stands for Multi-level Regression and Post-stratification, is a relatively recent innovation in polling science which have been used to successfully predict the last three British general elections, and gives the estimated result in each Westminster constituency.

Fieldwork was conducted from 4-11 September 2026, with a sample size of over 5,500 people.

1. Headlines

The poll places Labour in first place on 25pc, with Reform on 22pc, Conservatives on 20pc and Restore Britain on 7pc. On these figures, Labour is predicted to win 288 seats, leaving it 38 seats short of an overall majority, while the Conservatives are set to win 165 seats, Reform 84, and Restore 1 (Great Yarmouth).

The Liberal Democrats would win 61 seats, and the Greens 7 seats. The SNP would win 18 seats, and Plaid Cymru 7 seats.

The table below gives the prediction in numerical form:

Based on the numbers, if a general election were held now, the most likely outcome would be that no party has an overall majority. But the Labour party would be well-placed to form a coalition with the Liberal Democrats, which together would have a majority of 48 seats in the House of Commons.

2. Tactical Voting

Following a major polling project on tactical voting (TV) by Electoral Calculus and Find Out Now, we are able to estimate the effect of tactical voting on the predicted election result. Our TV analysis shows that:

The table shows the predicted vote share and seats won both without tactical voting and with tactical voting.

Without tactical voting, Reform would have 127 seats, but when tactical voting is factored in, Reform drops significantly to 84, a loss of 43 seats. Most of these seats would likely shift to the Conservatives, although some go to Labour as well.

3. Other Questions

Q3. "How likely would you be to vote for Restore Britain if there was a general election?"

Neither likely not unlikely7%11%4%17%4%

Don't know22%11%10%11%9%
Net Likely13%12%7%40%6%
Net Unlikely58%66%79%32%82%

If a general election were held now, 40pc of Reform voters would be likely to vote for Restore Britain, including almost a quarter (23pc) who would be "very likely" to do so. That figure drops to 12pc among Conservative voters who said they would be likely to vote for Restore Britain. Labour and Liberal Democrat voters were lowest, at 7pc and 6pc respectively.

Across the electorate as a whole, 13pc of voters said they would be likely to vote for Restore Britain, against 58pc who said they would be unlikely to. But with almost a quarter (22pc) still unsure, the figures suggest Reform remains Restore Britain's main target base, with potential to attract those who are undecided.

Q4. "Do you have a favourable or unfavourable opinion of Rupert Lowe, leader of Restore Britain?"

ResponseAll votersCONLABReformLIB
Very favourable6%5%2%22%2%
Favourable6%7%3%23%2%
Neither favourable nor unfavourable19%31%12%29%14%
Unfavourable7%13%7%6%10%

Don't know36%28%21%16%25%
Net Favourable12%12%5%45%4%
Net Unfavourable34%29%61%11%57%

When voters were asked whether they have a favourable or unfavourable opinion of Rupert Lowe, most voters (36pc) were undecided compared with 34pc who have an unfavourable opinion and only 12pc who have a favourable one.

Views differ sharply by party support. Nearly half (45pc) of Reform voters hold a favourable opinion of Lowe compared with just 11pc who say unfavourable. Conservative voters are a little more divided, with 29pc holding an unfavourable opinion, compared with 28pc who don’t know and 12pc who hold a favourable opinion. Unsurprisingly, the majority of Labour voters (61pc) and Liberal Democrat voters (57pc) have an unfavourable opinion.

4. Treatment of "Don't Knows"

Following polling errors in 2024, Electoral Calculus took part in investigations into possible causes, co-ordinated by the British Polling Council. Our findings are available here. In summary,

To incorporate these findings into our post-election polling, we have made two assumptions about those who answer "don't know" to either the turnout or voting intention questions.
