Jeffrey Epstein described Peter Mandelson as “devious” after lobbying a bank to underwrite a mining project launched by their mutual friend Nat Rothschild, emails included in the latest tranche of Epstein files suggest.

In April 2010, the then business secretary appears to have contacted banker Jes Staley, then at JP Morgan, from his personal email account in what appears to be an attempt to secure funding for Rothschild, Mandelson’s longtime friend.

Mandelson wrote to say that he was pleased to hear that JP Morgan was “planning” to underwrite a £700m investment vehicle being launched by Rothschild, a scion of the banking dynasty.

“I’ve been following my friend Nat Rothschild’s plans to list a vehicle on the [London Stock Exchange] and I’m very happy that JPM are now planning to get involved as book runners alongside [Credit Suisse],” Mandelson wrote to Staley. “I think it’s a great idea from what I see of the global mining business (and their prices). I hope it all goes well. Best Easter greetings to you and your family”.
