Out of 306 Conservative seats, Rishi Sunak’s current seat of Richmond (Yorks), at that time represented by former party leader William Hague, was the safest Conservative seat (by percentage majority).
South Holland and The Deepings and Rayleigh and Wickford were their second and third safest seats respectively, followed by Chelsea and Fulham, Beaconsfield, Broxbourne, Maldon, Aldridge-Brownhills, Witney and Windsor.
But since then a lot has changed. First, the 2024 election will be fought under new boundaries, with 76 constituencies enlarged, 73 reduced in size and a small number being largely new (with no obvious predecessor).
This means that some previously very safe seats are now not so safe, even before changes in voter intentions are considered. And voting intentions have significantly changed.
In 2010, the Conservatives won 36.9% of the vote in Great Britain (29.7% Labour, 23.6% Lib Dem), while current polls suggest this may now be as low as 20.0% (YouGov 27-28 May).
So what does this mean for safe Conservative seats? Well, there are not many to find.
MRP polling suggests that the Conservatives may be left with only 19 seats with a majority of 10% or more. Meanwhile, of their ten safest seats in 2010, they appear on course to retain eight and lose two (Chelsea and Fulham, and Windsor).

Adam Afriyie, MP for Windsor continually since 2005, was re-elected with 60.8% of the vote - a majority of 38.4% (19.054) over the Lib Dems.
How have boundaries changed?
Windsor’s constituency boundaries have been revised for 2024. For the updated Windsor constituency, 71% of people overlap with the previous Windsor constituency. Of the remaining 29%, 16% are from Runnymede and Weybridge and 13% are from Slough.
What is the current prediction?
Windsor is set to be a marginal seat. MRP polls generally point towards a Labour win, while the uniform national swing model suggests a Conservative hold.
