Jo Johnson, the brother of former United Kingdom prime minister Boris Johnson, has reportedly stepped down from his role as an adviser to Binance, according to a report by the U.K.’s Telegraph. 

According to the report, Jo Johnson had been advising Binance during the exchange’s efforts to expand into the United Kingdom. The former British prime minister’s brother, also known as Lord Johnson of Marylebone, reportedly took up a role on the U.K. advisory board of one of Binance’s subsidiaries, Bitfinity, in September. 

The Telegraph reports that he resigned last week after Binance’s proof of reserves raised red flags for some accounting and financial specialists amid a backdrop of negative sentiment impacting the exchange, which triggered a bank run shortly thereafter. 

In a statement issued on Monday, Lord Johnson shared: “ I stepped down from the advisory board last week and have no role with it [or] any related entity.”

Bitfinity, the company Lord Johnson was reportedly advising, was created by Binance in March 2022 and is “part of the Binance group,” as described in a filing with U.S. regulators in April. The company converts traditional currencies like the pound and the dollar into digital currency.
