Reform given record-breaking £36m donation by crypto billionaire

He had previously been convicted in the US before being pardoned by Trump

The donation, which was first reported by The Telegraph, is the largest ever one-off donation to be given to a party in British history.

Delo has also been convicted in the US for failing to implement adequate anti-money laundering controls, although he has since been pardoned by Trump.

The 42-year-old moved back to the UK from Hong Kong and has since dwarfed the £15m donation Reform previously received from Christopher Harborne.

The donation comes just a week after Reform and Nigel Farage found themselves at the centre of an undercover report and subsequent police investigation into alleged foreign donations to the party.

It had been suggested that Delo could have been caught out by the £100,000 donor cap implemented in March this year, which can only be avoided if someone has been on the UK domestic electoral register for at least 12 months. 

However, as per The Guardian, Reform appear confident that this will not be an issue after he gave £4m at the start of September.

Delo was convicted in 2022 in the United States for failing to implement adequate anti-money laundering controls in his cryptocurrency business BitMEX.

He has given Reform £8m since the start of the year, with this total now climbing to £44m.

Who is Ben Delo?

Ben Peter Delo is a 42-year-old crypto billionaire born in Sheffield in the UK.

He is a self-described entrepreneur and philanthropist who held an interest in coding and maths from a young age, going on to graduate from Oxford University in 2005.

Delo started out with a summer internship at IBM where he was subsequently hired as a software engineer.

He went on to develop automated trading systems for hedge funds and banks such as J.P. Morgan.

Delo moved to Hong Kong where he worked for J.P. Morgan and later set up BitMEX, a cryptocurrency trading platform, with Arthur Hayes and Sam Reed.

At its peak, BitMEX was valued at around £2.66bn, with Delo being credited with inventing the 'perpetual swap' - a type of financial derivative contract that lets you speculate on an asset's price without an expiration date.

However, BitMEX is set to shut down on 23 September.

While it did not give a reason for the closure, it would not have been helped by the regulatory charges it has faced in the past.

Delo was charged in 2020, along with three others, with not implementing an adequate anti-money laundering programme for BitMEX.

He pleaded not guilty after travelling to the United States and surrendered himself to authorities in New York, although was allowed to return to the UK.

Delo later pleaded guilty to the charge of not implementing an adequate anti-money laundering programme in 2022, paying a $10m fine and receiving 30 months' probation before being pardoned by Trump last year.

Delo is a self-described philanphropist, as per his LinkedIn profile, and has given millions away as part of The Giving Pledge campaign.

It would seem now, however, that he has found a new pot to throw money at - Reform UK.
