The problem with living in a so-called “safe” seat is that there’s not a great deal of reason for your MP to feel they have to work for their constituents. That’s by no means true of all MPs in safe seats, but if re-election is all but assured, the danger is that these MPs are more bothered about the interests of their parties or themselves than the places that they represent.
The two present Southend parliamentary constituencies — Southend West and Rochford & Southend East — have never returned anything but Conservative MPs. Indeed, for anything different you have to go back to 1945, when the seat of South East Essex covered part of Southend and returned Labour’s Ray Gunter.
So given that it has been 70 years since anything but a Tory MP represented any part of Southend, and present MPs Sir David Amess and James Duddridge both sit on hefty majorities (14,021 and 9,476, respectively), it seems fairly clear to me that both constituencies are Conservative safe seats.
Like I said, that doesn’t mean that MPs have to be disinterested in the town. Which makes it all the more disappointing that they apparently are.
