LONDON (AP) — Reform UK, the anti-immigration party led by Brexit campaigner Nigel Farage, received 72 million pounds ($97 million) from two cryptocurrency billionaires this weekend, fueling concerns about money in British politics.

After news broke that Ben Delo, a co-founder of the BitMEX cryptocurrency platform, had given 36 million pounds ($48 million) to the party, crypto investor Christopher Harborne on Saturday announced he was matching the donation.
