Irish rap trio Kneecap have said they are “banned” from advertising one of their posters on the London Underground.

Yesterday, in a social media post, they said: “We’ve been banned from advertising on the London Tube.”

Transport for London (TfL) said it approves adverts on a “case-by-case basis” and deemed the Kneecap poster, showing their frequently used logo depicting a balaclava to promote a September concert, “would likely cause widespread or serious offence to reasonable members of the public”.

The poster shows their logo, based on the balaclavas worn by paramilitaries during the Troubles in Northern Ireland, and reads: “Kneecap. OVO Arena Wembley, London. Thurs 18th September ’25.”

The balaclava-style logo has been used previously on the TfL network in a smaller size, in promotional adverts for the band’s summer 2024 movie.

A TfL spokesperson offered no further comment when asked about this.

In a statement, the group said: “How petty can political policing and interference get.

“After using the Tube to advertise loads of times for gigs, records and our movie, all without issue.”

In May, Liam Og O hAnnaidh, who performs under the stage name Mo Chara, was charged with a terror offence for allegedly displaying a flag in support of Hezbollah at the O2 Forum in Kentish Town, north London, during a gig in November 2024.
