Young people have lost faith in Donald Trump, polling shows.

The US president’s approval rating among 18 to 29-year-olds fell from roughly even around the time of his inauguration in January to minus 40 by July, according to analysis of YouGov data by the pollster G Elliott Morris.

Gen Z voters swung towards Mr Trump in last year’s election, even though support for Republican candidates tends to lag among younger voters, but this has collapsed in the months since.

Mr Trump is facing the biggest crisis of his second term over his handling of the Epstein files, with his administration refusing to make public all of its documents relating to Jeffrey Epstein, the paedophile financier, who died in 2019.

By the US president’s own account, he was friends with Epstein for about 15 years before they fell out in the early 2000s.

The drop in support could be a hopeful sign for the Democrats, many of whom were panicked by Mr Trump’s support among younger voters when he won last year’s presidential election, almost equalling his opponent Kamala Harris for support among 18 to 29-year-olds.
