Britain has the most miserable millenials in Europe, a worldwide survey has found, with experts blaming “the age of anxiety” for increasing pessimism.

Increasing concerns about climate change and the uncertainty surrounding Brexit have been blamed for 73% of youth in the UK saying they feel pessimistic about the future.

The survey, conducted by Barna group - a faith-based research centre - and World Vision UK, a charity which improves the lives of vulnerable children, is the biggest study of its kind. It surveyed 15,000 18-35 year olds across 25 countries in nine languages.

The UK came second to last in the world rankings when millenials and Generation Z youths were asked to either agree or disagree with the statement: ‘I often feel optimistic about the future’.

Just 27% of UK youth agreed with the statement. The only other country to receive a lower score - of 26% - was South Korea.
