TRNSMT and Belladrum festivals cancelled due to Covid-19
The TRSNMT music festival, which was due to be headlined by acts including Lewis Capaldi and Liam Gallagher, has been cancelled due to Covid-19.
The Glasgow Green event had been expected to attract up to 150,000 fans over three days.
But in a statement organisers said they were "absolutely gutted" it would not go ahead as planned from 10-12 July.
Hours later, the Belladrum Tartan Heart Festival in the Highlands was also postponed as a result of the pandemic.
The announcements follow First Minister Nicola Sturgeon's briefing on Thursday that large public gatherings were likely to be banned or restricted and that social distancing could remain in place for the remainder of the year.
Other acts on the TRNSMT line-up included The Courteeners, Snow Patrol, Ian Brown, Rita Ora and Sam Fender.
A statement posted on the TRNSMT website said: "We did not want to take this step but it is unavoidable. The health and safety of our fans, artists, staff and community will always be our top priority.
"We are now working hard with all the artist teams to try to get the 2021 line-up as close to this year's as we can and will be able to update on this fully over the next two weeks."
Fans who bought tickets will have the option of holding onto them for the 2021 event, which is scheduled for 9-11 July, or requesting a refund.
Ticket providers should be in touch via email and people are being advised only to contact them if they have not heard anything back after 14 days, organisers said.
The statement concluded: "TRNSMT would not be the amazing festival that it is, without you - our amazing audience so we thank you for your support. Stay at home, practice social distancing and stay safe.
"We will be back next year to celebrate like never before - see you all then!"
'Absolutely devastated'
Meanwhile, the Belladrum team said they were "heartbroken" at having to cancel.
Among the acts due to perform at the event, near Beauly, from 30 July to 1 August were Nile Rodgers & Chic, Emeli Sande, Shed Seven and Passenger.
A statement on the festival website said: "We had been progressing with plans to deliver our 17th outing but as the pandemic plays out across the UK, it has now become clear that delivering the event in 2020 simply isn't going to be possible.
"The health and safety of our Belladrum Family, staff, suppliers and local community are our number one priority
"Whilst we are absolutely devastated to not be able to go ahead this year, we have to look forward to safer times in 2021."
As with TRSNMT ticket holders can transfer their tickets to the 2021 event, which is set for 29-31 July, or request a refund.
