British 14- and 15-year-olds are more socially conservative than any generation except the over-70s, researchers have claimed.

The study, whose findings were published in the Times, suggests that interviewees born since 2000 were less sympathetic towards gay marriage, transgender rights and the legalisation of cannabis than those aged 16 to 70.

The researchers interviewed more than 2,000 people – a smaller number than other large-scale comparisons of social groups. The exact figures have not been published.
