“Labour has lost the working class”
Over the years, but particularly in the Brexit era, older people have swung to the right and younger people to the left.
In 1983 18-24 year olds backed Thatcher over Labour by 9 points, while over-65s backed Labour by 6. This time 18-24s backed Labour 57-19, while over-65s backed the Tories 62-18! Among women voters aged 18-24, only 15% went Tory.
Older people are more and more over-represented in areas where Labour lost the bulk of its seats, and young people more and more under-represented. And older people are much more likely to turn out and vote.
