The UK’s summer music calendar will miss one of its most popular and unique events after this year with the news Festival No.6 is to end.

The Portmeirion, North Wales event launched in 2012 and has attracted acts such as Noel Gallagher and the Pet Shop Boys, as well as up to 10,000 attendees each year.

Its final staging will be in September, with Franz Ferdinand, The The, and Friendly Fires headlining.

Organisers left the door open to it one day returning by saying it will the last event “for now”, but said that the Portmeirion site, a small coastal village, “was not sustainable in its current format”.

They said: “It has far outgrown its intimate capacity.

“Portmeirion is a complex site and we’ve had fun adapting and reinventing the festival every year but unfortunately No.6 is just not sustainable in its current format and so we’ve made the difficult decision to take a breather – 2018 will be the last Festival No.6 for now.

“We will of course be throwing an almighty party this year and will make sure it’s the most outstanding No.6 to date!”
