US congressional committee files reportedly show a US ambassador referring to Epstein as his “best pal”, and Mandelson was featured in Epstein’s 50th birthday book compiled by Ghislaine Maxwell.
Appearing on Sky News, Mr Streeting said that Lord Mandelson “deeply regrets ever having been introduced” to Epstein.
Mr Streeting rejected calls for Mandelson’s removal from his ambassadorial role, arguing that individuals should not be considered “guilty by association”.
