T in the Park bosses have blamed bad weather for a slow clear-up at the festival’s Strathallan Castle site.
Event organisers spoke out after they were accused of breaking a promise to restore the estate to its former glory within a matter of days.
In a letter to residents ahead of this summer’s live music extravaganza, show director Geoff Ellis pledged to have the 1,000-acre estate cleared within two weeks.
“There will be nothing to indicate that we’ve been there at all,” he said.
Now, nearly three months after about 80,000 fans descended on the grounds, campaign group Stag has alleged that Mr Ellis has failed to live up to his pledge.
In this video, the group which battled to stop thefestival’s relocation claim that broken fences and rubbish were still visible around the estate earlier this month.
Campaigners say that parts of discarded tents were blown away by high winds and found up to four miles away.
A spokeswoman for the group said: “Strathallan is now a broken landscape, as the result of broken promises.”
A spokeswoman for T in the Park said that the clear-up operation had been hit by bad weather.
“The bulk of the clean-up was done in the first two weeks following the festival and we are really pleased with the progress,” she said. “The final stage has taken longer than we expected due to the wettest July Scotland has seen in recent years but it is almost complete.
“Our partners in Perth and Kinross Council’s planning and waste departments have been kept up to date and they are fully aware and accepting of the situation.”
Tory culture spokeswoman and local MSP Liz Smith said: “Very specific commitments were provided by DF Concerts that the site would be fully cleaned and restored to its original state within the given timescale.
“This footage (shot by Stag) clearly shows this is not the case and that is something which is unacceptable, not least because it is causing further upset to locals and to those who frequently use the surrounding access roads.”
The new accusations come as Culture Secretary Fiona Hyslop appears before a committee of MSPs to explain why the event was given £150,000 of public money.
