New analysis from YouGov will make worrying reading for the parties hoping to cause an upset in next month's General Election, as all five seats are predicted to be held.
It suggests Boris Johnson is on course to win the election with a comfortable 68-seat majority by triumphing in Labour heartlands.
In Ludlow the Conservative candidate Philip Dunne would take 60.18 per cent of the vote share in YouGov's model, while the contest would be closest in Shrewsbury and Atcham, with the Conservative Daniel Kawczynski to take 49.45 per cent of votes and Labour challenger Dr Julia Buckley on 32.54 per cent.
The figures have come from YouGov's multilevel regression and post-stratification (MRP) model, which is based on extrapolating the voting intentions of 100,000 people across the country who were polled over the course of a week.
They say Conservatives Lucy Allan and Mark Pritchard would hold their Telford and The Wrekin seats with 54.85 per cent and 58.78 per cent respectively.
In the 2017 election Telford's MP Lucy Allan increased her vote share to 48.7 per cent. Mark Pritchard for the Wrekin also increased his share, to 55.4 per cent.
North Shropshire would be held by Owen Paterson with 56.52 per cent.
His share of the vote in 2017 was 60.5 per cent. The Labour candidate he faced in the last two elections, Graeme Currie, would win 24.77 per cent of the vote this time around under YouGov's model.
Labour would be the second party in each Shropshire constituency except Ludlow, where Liberal Democrat challenger Heather Kidd would be the runner-up with 21.3 per cent.
The Liberal Democrats would be limited to single-digit results in Telford and The Wrekin. The former is a three-horse race between Conservative Lucy Allan, Labour's Katrina Gilman and Lib Dem Shana Roberts.
In nearby Montgomeryshire, the new Conservative candidate Craig Williams would take 52.69 per cent of the vote and the Liberal Democrat Kishan Devani would come second with 30.52 per cent.
YouGov warned that its MRP method is not "magic" and that the sample sizes for individual constituencies are small, though it did correctly call that the 2017 election would result in a hung parliament.
YouGov said it is not a prediction or a poll but an estimate on what might happen if the election happened today.
Nationally the picture is grim for Jeremy Corbyn's Labour party, as Boris Johnson is predicted to win 359 seats – a majority of 68.
How does it work?
Professor Ben Lauderdale of YouGov, who co-created the MRP method, explained the model's methodology.
"For the last seven days YouGov has interviewed approximately 100,000 panellists about their voting intentions in the 2019 General Election. While this is a much larger sample than our usual polls, the samples in each of the 632 GB Parliamentary constituencies are too small (on average, only 150 voters per constituency this week) to produce reliable estimates if we analysed the data as constituency polls.
"The idea behind MRP is that we use the poll data from the preceding seven days to estimate a model that relates interview date, constituency, voter demographics, past voting behaviour, and other respondent profile variables to their current voting intentions. This model is then used to estimate the probability that a voter with specified characteristics will vote Conservative, Labour, or some other party.
"Using data from the UK Office of National Statistics, the British Election Study, and past election results, YouGov has estimated the number of each type of voter in each constituency.
"Combining the model probabilities and estimated census counts allows YouGov to produce estimates of the number of voters in each constituency intending to vote for a party.
"In 2017, when we applied this strategy to the UK general election, we correctly predicted 93% of individual seats as well as the overall hung parliament result."
He warned that the MRP model does have its weaknesses.
He said: "Despite the strong performance of the method in the 2017 election, it is not magic and there are important limitations to keep in mind.
"First, we are reporting estimates of current voting intentions, not a forecast of how people will vote on December 12. Panellists tell us how they intend to vote on December 12, but they may change their minds and we do not attempt to quantify the probability that they will do so.
"Second, the samples in each constituency are too small to be reliable by themselves and are subject to more than just sampling error. To compensate for small sample sizes, our model looks for patterns in the data across constituencies. Our sample is large enough that we can identify patterns that occur across relatively small numbers of constituencies, but the largest model errors are likely to occur in constituencies with very atypical patterns of voting.
"Some examples of these are seats where there is a high profile independent candidate or where there appears to be a new pattern of local competition in this election."
This would be the Conservative Party’s best performance in 30 years
The constituency-by-constituency estimate by YouGov, published in The Times, indicates that if the election was held on Thursday, the Conservative Party would win 359 seats, 42 more than they took in 2017.
It would also take 43 per cent of the vote, and in number of seats this would be its best performance since 1987.
Labour, meanwhile, is set to lose 51 seats, falling from 262 seats in 2017 to 211 now, and taking 32% of the vote, a nine percentage point decrease.
This would be the party’s worst performance in seats won since 1983, YouGov said, adding that the opposition is on course to not take any new seats.
Of the 76 Labour-held seats where it leads the Tories by fewer than 8,000 votes, Jeremy Corbyn’s party is currently behind in 43 of them, according to the analysis which has been released just over two weeks before polling day.
YouGov used the same method in the 2017 general election, when it accurately predicted the results in 93% of constituencies and pointed towards a hung Parliament.
Chris Curtis, political research manager at YouGov, said the current analysis shows the Tories have a “comfortable majority”, with seats coming their way at the expense of Labour in the North and Midlands.
“As expected, the key thing deciding the extent to which each of these seats is moving against Labour are how that seat voted in the European Union referendum.
“In the seats that voted most strongly to Leave in 2016 (60% or more in favour of departing the EU), the swing to the Conservatives is over 6%.
“This is allowing the Tories to overturn quite substantial majorities in places like West Bromwich East, the seat held until recently by Tom Watson, and Don Valley, the seat currently held by Caroline Flint.
“The only silver lining for Labour is that there are still 30 seats where it is currently 5% or less behind the Tories.
“If it can manage to squeeze the gap over the coming fortnight, it may be able to paste over the cracks in their so-called Red Wall. But with just two weeks to go, time is running out for Labour.”
Shadow Health Secretary Jonathan Ashworth said if the poll is correct it will be a “thumping great victory” for Prime Minister Boris Johnson.
He told ITV’s Peston that people are going to have to start thinking about whether they really want Mr Johnson for the next five years running the NHS which he said has waiting lists of 4.5 million, adding: “How much worse are those waiting lists going to get if Boris Johnson has got a victory of that size?”
Baroness Warsi, former Conservative Chair, told the programme it is good news and bad news for the Tories, explaining: “Good news because I think secretly we’ll be quite confident that this is exactly where we needed to be at this stage, and so far the election campaign has gone to plan.”
But she said it is bad news as there will now be a concern that people who would have voted Tory may now feel they do not need to bother.
Meanwhile, the Liberal Democrats are currently on course to see their number of MPs increase by just one from 12 to 13, picking up four new seats while losing out in three they currently hold.
The SNP is on course to secure a further eight seats, although crucially for the Tories’ chance of securing a majority, only two come from Mr Johnson’s party (Stirling, and East Renfrewshire).
By contrast, Labour is set to lose five seats to the SNP, with the Lib Dems losing one in Scotland, the figures show.
The Greens will still have one seat, while Plaid Cymru will still have four, according to the data.
A separate poll, by The Daily Telegraph and Savanta ComRes, has the Conservatives on 41%, down one point from the weekend, while Labour rises two points to 34% at the expense of the Liberal Democrats, who drop two points to 13%.
The pollster said that according to voting analysis website Electoral Calculus, if the parties were to achieve these vote shares at a general election it would result in the Tories having a narrow majority of 10.
The projections came as Mr Johnson’s top aide Dominic Cummings warned the election race was “much tighter” than the opinion polls suggested.
He said Leave supporters risked handing victory to Labour if they voted for Nigel Farage’s Brexit Party in key marginals the Tories need to take if they are to gain an overall majority.
The YouGov model seems to suggest the Brexit Party is hurting the Conservatives more than Labour in some neck-and-neck marginals where Nigel Farage’s party is running.
Meanwhile, Mr Corbyn said he “regrets” incidents of anti-Semitism in the Labour party, but again stopped short of personally apologising in the wake of Chief Rabbi Ephraim Mirvis’s criticism.
Key figures on the Labour leader’s frontbench apologised on Wednesday, after Mr Corbyn refused to do so four times during his interview with the BBC’s Andrew Neil.
Elsewhere, the Daily Express reported that Mr Johnson said public spending cuts under David Cameron and George Osborne were “not the right way forward” for the country.
Former Tory David Gauke was asked on ITV’s Peston if he had noticed Mr Johnson opposing austerity when they were in Cabinet together.
He replied: “I didn’t particularly. I think in terms of the early years of the coalition Government when I was in the Treasury I didn’t have a lot to do with Boris Johnson at that point.
“But I would make the point that there’s not a lot of fiscal discipline coming from Boris Johnson at the moment, so maybe there is some consistency here.”
On Thursday night, Mr Corbyn will join other party leaders, not including Mr Johnson, for the first election leaders’ debate focusing on the climate crisis, which will be broadcast on Channel 4.
