In May 2019 British broadcaster Channel 4 News reported it had seen invoices for travel and accommodation expenses between summer 2016 and summer 2017. It further reported that these benefits, worth "as much as £450,000", were funded by Arron Banks, and were not declared on Farage's register of interests, which he should have done as a serving MEP. Liberal Democrat MEP Catherine Bearder, in her role as a quaestor (an MEP responsible for financial and administrative matters), raised the issue and this resulted in an official investigation opening on 21 May 2019. When asked by the BBC about the matter Farage replied, "Whatever happened after the referendum – I was leaving politics, it happened mostly in America, it had nothing to do with politics, nothing to do with the Brexit Party, it was purely on a personal basis. I was looking for a new career and a new life – it's got nothing to do with anything, it's a purely private matter."
