Sir James Dyson's libel claim against the Daily Mirror's publisher, Mirror Group Newspapers (MGN), has been dismissed by Mr. Justice Jay. The legal action stemmed from an article published in January 2022, which Dyson deemed a personal attack on his lifetime achievements. In the two-day trial, Justin Rushbrooke KC, representing Sir James, argued that the article constituted an unjustified slur on his reputation, both personally and professionally. The piece, written by Brian Reade, referred to Dyson as the "vacuum-cleaner tycoon" who championed Vote Leave and later relocated his global head office to Singapore. The court, however, sided with MGN, asserting that Sir James failed to demonstrate financial loss or harm to his philanthropic work.
