New Epstein files show Mandelson repeatedly ‘insider trading’ and helping banks beat taxes

Documents in the latest Epstein file release show Keir Starmer’s disgraced senior adviser Peter Mandelson engaging repeatedly in likely ‘insider trading’ with Epstein, who was closely and corruptly linked to big banking and big business. At least, that’s according to finance expert and investigative journalist Dan Neidle.

A number of commentators have pointed out that the files show Mandelson boasting of persuading Gordon Brown to resign as prime minister, including the Times’s Gabriel Pogrund. But, as Neidle pointed out in response, they show far more than that.

Instead, they show Mandelson providing financially sensitive – and potentially highly profitable – insider information to a Wall Street trader:

Gabriel understates what happened here. We can tell from this version of the same email chain that Mandelson’s last email was sent 16:02:52 BST

Brown’s resignation was public 19:19 BST.

Mandelson’s sickening power

Knowing that Brown was about to resign – with its likely ‘blip’ in UK stock market prices – would have given Epstein and anyone else he informed the opportunity to ‘sell short’. Short selling involves selling shares a trader doesn’t own yet, in the expectation of buying them for a lower price later because of news that shocks the market.

This is not theoretical. In another grossly anti-semitic email thread, Epstein boasts to another Jewish contact that “the Jew make money” by “selling short” while the gentiles – “goyim” – “deal in the real world”:

The Times‘s political editor Steven Swinford and Novara‘s Aaron Bastani picked up on another email showing Mandelson tipping off Epstein about a coming $500bn bail-out “to save the euro” – and “threatening” then-chancellor Alistair Darling on behalf of a huge bank to reduce a planned tax on bankers’ bonuses:

Mandelson was seemingly involved in insider trading, while helping Epstein, and by extension Jamie Dimon, intimidate his colleague, Alistair Darling, over a tax on bankers bonuses.

The bail-out tip-off would have given Epstein and his coterie the opportunity to buy shares – the opposite of selling short – at the existing price, knowing that news of such a huge bailout would push prices up and create an immediate profit.

Neidle added that the threatening of Darling directly benefited Epstein as well as his banking sponsor:

New Epstein emails show Peter Mandelson secretly advising JPMorgan’s CEO on how to fight Labour’s 2009 bankers’ bonus tax – even suggesting he “mildly threaten” the Chancellor.

Both the short-selling and the bail-out tip-off fall under the category of ‘insider trading’. Insider trading is a serious criminal offence. At the time Mandelson was providing this information to Epstein, the criminal penalty was an unlimited fine and up to seven years in prison. The potential prison time has since increased to ten years, but only for offences committed from 2021. The Mandelson emails were in 2009 and 2010.

Police are ‘investigating’ whether Mandelson’s actions are prosecutable. There can be no excuses for failing to charge him.
