The event is billed as the first of its kind since 2018, and is due to see 39 acts perform over the weekend of 5 and 6 June.

It will “celebrate the deep cultural bond between Ireland and Liverpool through music, dance, food and community” and include “lively céilí and folk anthems, contemporary Irish pop and rock”.

But in its representation to licensing chiefs, Merseyside Police it objected to the hours because “there is reason to believe that allowing up to 5,000 people to leave a site all together will increase the likelihood of crime and disorder”.

It added it feared loud music and late alcohol sales would “contribute to anti-social behaviour and complaints from residents by disturbing the peace after an acceptable time of night”.

Police said they wanted alcohol sales to end at 21:30 and “all music / dance” to finish at 22:00, with everyone off-site by 23:00.
