A US federal judge has dismissed a lawsuit brought against JPMorgan, which accused chief executive Jamie Dimon and his board of not heeding warnings around their former client, the late convicted sex offender Jeffrey Epstein.

The case centres on accusations that Dimon and other directors — including former private and investment bank chief Jes Staley — “put their heads in the sand” as Epstein continued banking with JPMorgan, using his accounts to continue his abuse of young women and girls.
