No large arena in the UK has enough of a gap in its event listings to host Eurovision next year, with organisers telling the BBC that a venue would be needed by producers six to eight weeks ahead of the song contest.
Shows involving Celine Dion, Magic Mike, André Rieu and Elton John would all need to be rearranged by Glasgow during the six to eight-week period needed for any potential venue.
The city entered a bid in July and will find out on Friday if it has been shortlisted – but a decision will not be made until the autumn about which city will be hosting the event.
Tickets for all the shows that would need to be rescheduled remain on sale, with no indication of a preferential choice.
Claudio Santucci, this year's head of show, told the BBC: “The set up takes around three weeks, then three or four weeks of rehearsals, but one of those weeks is the show.
"It's a long period of rehearsals to make it work”.
Mr Santucci added: "It's an event that would normally take two years to organise, but instead you have less than a year because you only know when you win."
Detailing the requirements the host city must meet to be considered, the BBC said: “The final decision on selecting the host city will be based on a city or region’s capacity and capability in meeting the BBC’s and the EBU’s [European Broadcasting Union] requirements, as well as availability of resources and general experience in hosting a large and complex event such as the Eurovision Song Contest.
“For example, last year the EBU’s host city criteria was based on providing a venue able to accommodate at least 10,000 spectators (as well as a press centre), that should be within easy reach of an international airport and with ample hotel accommodation.”
The broadcaster also said it may “consult” the UK Government on the decision, but the host city will ultimately be decided upon by the BBC and the EBU.
