‘Finally got him to go’: how Epstein was given an inside track on UK’s political future

Apparent tip-off by Peter Mandelson gave advance notice of instability that would ripple through global markets

On a brisk Monday evening in May 2010, Gordon Brown stood on the steps of Downing Street and delivered one of the most dramatic announcements of the New Labour era: his resignation as UK prime minister.

The decision came days after a nail-biting general election that left no single party with a clear run at No 10. Brown kept his decision, which followed days of political wrangling, to a tight inner circle. Nick Clegg, who would go on to serve as deputy prime minister of the Conservative-Liberal Democrat coalition, was formally told of Brown's resignation only 10 minutes before the announcement.
