BBC Panorama investigation

In August 2018, a BBC Panorama documentary investigation revealed Jessen's involvement in a private online pharmacy, UK Meds. Such sites are believed to allow people to purchase potentially dangerous prescriptions with ease and cannot be regulated by the Care Quality Commission due to a loophole allowing them to issue prescriptions via third party doctors in Romania.^[16][17] The owner of the pharmacy, Mason Soiza, has previously faced accusations of running escort agencies and WordPress plugin scams.^[18][19]

A spokesperson for Dr Jessen told Panorama "he was engaged by UK Meds to present short information videos about various medical conditions and that he does not prescribe medication, nor does he endorse a specific product, service or brand." Source: https://www.bbc.co.uk/news/health-45084555

COVID pandemic

Arlene Foster

In 2020, the First Minister of Northern Ireland Arlene Foster launched legal action against Jessen for defamation over a tweet in December 2019 that falsely claimed she had been having an extra-marital affair.^[21] The tweet was not deleted until two weeks after it was posted. In court, Foster alleged that the tweet was posted at a time when some anonymous Twitter accounts were claiming she was having an affair with one of her security guards. It was further alleged that Jessen had been contacted 13 times by email and letter about it but had not answered.^[22] In May 2021, Mr Justice McAlinden awarded Foster £125,000 in damages and full costs after Jessen lost the case, describing his conduct as "an outrageously bad libel". The judge added that Jessen's failure to apologise for or to retract the libel were aggravating features.^[23]
