UK General Election 2017 Seat Forecast #5 – North Norfolk, East England

May 13, 2017 By Nigel Marriott

This is my first seat forecast from the Eastern region and I have chosen the seat of North Norfolk for two reasons.  First it is one of only 8 seats held by the Lib Dems in 2015 and one of 3 Lib Dem-Leave seats.  Second, it is one of 23 seats in Britain this election that will be fought between only 3 candidates from the Conservatives, Labour and Liberal Democrats.  Both UKIP and the Greens have decided not to stand in this seat and this will be a good seat to examine my model for handling the votes of parties that stand down.

My Prediction – CON GAIN but extremely marginal

UK General Election 2017 Seat Forecast #4 – Bishop Auckland, North East

May 10, 2017 By Nigel Marriott

This forecast was updated on 17th May 2017.  The predicted outcome is unchanged from my previous forecast.

For my 4th seat forecast of the 2017 general election, I am heading to the North East which is where I grew up.  A colleague who lives in the Bishop Auckland seat told me that “Labour could put a monkey up as a candidate and it would get elected”.  Since the seat was created in 1885, no Tory has ever won this seat and it has been Labour since 1935.

My Prediction – CON Gain

UK General Election 2017 Seat Forecast #3 – Cardiff South & Penarth, Wales

May 8, 2017 By Nigel Marriott

This is the third of my seat forecasts for the 2017 general election and my first for a Welsh seat.  By co-incidence the second Welsh Barometer poll was published today so I am able to explore this seat using a Welsh specific poll.

My Prediction – LAB Hold but now a very close marginal for what used to be a safe Labour seat

UK Weather Tracker #3 – April 2017

May 7, 2017 By Nigel Marriott

Spring has arrived and so far, we can say that it has been a pleasant spring.  My latest UK weather tracker shows that it was the 5th warmest April since 1910.

UK General Election 2017 Seat Forecast #2 – Kensington, London

May 2, 2017 By Nigel Marriott

This is the second of my seat forecasts for the 2017 general election.  I have to be honest, it never occurred to me that I would be covering Kensington as that seems a straightforward seat to forecast.  However, Kensington now has the distinction of being the first seat to have a constituency poll published and the results provide an insight as to which might be the best forecasting model to use.

My Prediction – Straightforward CON Hold but first signs that this is a Brexit realignment election

UK General Elections #1 – How accurate are the opinion polls?

May 1, 2017 By Nigel Marriott

The French pollsters are congratulating themselves for getting the first round of the French Presidential Election right last weekend.  Recently Nate Silver criticised the accuracy of polling in the UK.  For British pollsters, 2015 was a year they would like to forget and I am sure many of them will be nervous of the forthcoming general election but how nervous should they be?

I was one of the few people to predict the polls would be wrong in 2015 though the magnitude of the error was larger than I expected.  Two years ago I based my conclusions on an analysis of polls between 1992 & 2015 but for the 2017 election I have analysed a longer time period from 1950 to 2015.  I have made use of the excellent work done by Mark Pack who has systematically recorded every opinion poll published since 1945.  Based on this, I am expecting the polls to be in error again with the Conservative lead over Labour underestimated by 2.6%.

UK General Election 2017 Forecast #1 – Prediction as of 28th April 2017

April 30, 2017 By Nigel Marriott

Here you can find my latest forecast of the 2017 UK General Election on 8th June.  My forecast uses data from my latest UK Opinion Poll Tracker and it is worth reading that post in conjunction with this post.

My latest prediction using uniform regional swing is that the Conservatives will make a net gain of 78 seats resulting in a working majority of 171 seats.  Such a majority would be on a par with Tony Blair’s landslides of 1997 & 2001.   If anti-Conservative tactical voting takes place then this has the potential to reduce the Conservatives working majority to 135 seats which I am sure Theresa May would be very happy with!

UK Opinion Poll Tracker #3 – 28th April 2017

April 30, 2017 By Nigel Marriott

The Prime Minister has called for a General Election on 8th June 2017 and parliament has approved this.  For the next 6 weeks, opinion polls will be coming in thick and fast and I will do my part by keeping my opinion poll tracker up to date and explaining what the latest trends are.  I will use these trends to update my 2017 General Election Seat Predictions and you should read that post in conjunction with this one.

The latest situation is that the Conservatives hold an 18% lead over Labour and are on track for a working majority of 171 seats.  Labour are set for their worst general election vote share since 1918 and the Lib Dems have overtaken UKIP to regain 3rd place in the polls for the first time since December 2013.

UK Weather Tracker #2 – March 2017

April 9, 2017 By Nigel Marriott

Spring has arrived and so far, we can say that it has been a pleasant spring.  My latest UK weather tracker shows that it was the 5th warmest March since 1910.

UK Opinion Poll Tracker #2 – 28 March 2017

March 24, 2017 By Nigel Marriott

On the eve of Article 50 notification and with speculation about an early election being called, my latest opinion poll tracker predicts the Conservatives would have a working majority of 143 seats if an election was held today.  Since the Stoke Central by-election last month, it appears that some UKIP voters are switching to the Conservatives, the Lib Dem recovery is taking a breather and the 5 year decline in Labour’s fortunes shows no sign of coming to an end.
