Analysis from the Scottish Conservatives shows that Scottish Labour leadership candidates have made substantial costed spending promises amounting to £3bn.
Richard Leonard has already spent £1.6bn and Anas Sarwar MSP has already spent £1.4bn on an array of costly promises.
They have also promised mass nationalisation, including PFI contracts, ferries and rail services that would cost billions in additional spending. Mr Leonard himself has estimated his plans to buy out PFI contracts would cost £29 billion – almost equivalent to the entire budget of the Scottish Government.
In addition to casually spending hard-working taxpayers money, Anas Sarwar proposes massive increases in income taxes which would increase taxes for anyone earning over £28,000 and cost £350 for taxpayers earning over £40,000.
Meanwhile, Richard Leonard has promised to implement a wealth tax of 1% on the highest earners, which is not only illegal but would also lead to a mass exit of capital.
Commenting on the findings, Shadow Finance Cabinet Secretary Murdo Fraser said:
"Together the two Scottish Labour leadership contenders have racked up a £3bn bill in just two months.
"This is clear evidence that, regardless of the outcome, Scottish Labour's dogmatic determination to nationalise and spend will wreck Scotland's economy.
"Their inevitable tax rises are not progressive, they are punitive, and will seriously impact the standard of living of all hardworking taxpayers.
"In addition, both leadership hopefuls display a profound misunderstanding of Scotland's economy. With mass nationalisation of this scale, future tax rises are inevitable.
"What this really demonstrates is the ongoing competition between the SNP and the Scottish Labour Party, regarding who will tax the most.
"It is only the Scottish Conservative Party that will revitalise the economy and put sound economic management at the heart of government."
