Further revelations were made public on 25 October 2017. He was found to have used racist insults on a Morrissey fan site in 2002, saying that Danes were "pig shaggers" who "practised bestiality" and referring to Spaniards as "dagos". O'Mara, when reviewing the Arctic Monkeys in November 2004, made several sexual comments including how "sexy little slags" danced to the band's songs. These revelations resulted in O'Mara being suspended from the Labour Party and therefore having the party whip withdrawn. After the party whip was suspended, O'Mara cancelled his constituency surgery and would not speak publicly again for some months afterwards. It also came to light that O'Mara was a member of a band called Dirty Rotten Troubadours. A song by the band emerged, allegedly sung by O'Mara, contained the lyrics: "I wish I were a misogynist / I'd put her in her place / I wish I were a misogynist / I'd smash her in her face."
