The SNP has claimed the “toxic legacy” of using private finance initiative deals to build schools will cost it about £12.1million this year.
Banffshire and Buchan Coast MSP, Stewart Stevenson, blamed opposition parties on the council of “short-term thinking and profligate use of public money”.
It came as analysis by the Scottish Parliament Information Centre revealed local authorities will pay more than £400million this year towards PFI schools.
The SNP scrapped the PFI system upon taking power in 2007.
Mr Stevenson said: “The toxic legacy of the PFI deals have left our schools and Aberdeenshire Council to pay millions of pounds every year – proving once again that only the SNP can be relied upon to deliver on education and local funding.
However, the council’s Conservative group leader, Jim Gifford, accused Mr Stevenson of “inventing facts to create his local version of the national story being put out by the SNP”.
He added: “The last PFI school, unless we have missed something, was Meldrum Academy and that was completed prior to 2007 – the Conservatives were not part of the Aberdeenshire Council administration prior to 2007.
“In his desire to have a go at us, he has clearly failed to check that small, but vital fact.”
The council’s Lib Dem group leader, Karen Clark, accused Mr Stevenson of trying to “divert attention from the failure of SNP education policy”.
She added the “best funding mechanism offered to councils” at the time had been PFIs.
