The venue chosen had a capacity for 10,000 attendees.[2] Momentum had banned journalists from The Sun newspaper from having access to the festival due to its reporting of — and subsequent lack of apology for — the 1989 Hillsborough Disaster.[1] One of the events hosted by TWT was a "Radical Bus Tour with Dan Carden". Carden, the MP for Liverpool Walton, gave a bus tour covering the key locations of protest, struggle and social progress in Liverpool.[32]
