Liz Truss and Rishi Sunak have railed against Nicola Sturgeon and the SNP ahead of tonight's Conservative leadership hustings in Perth.
Ms Truss promised new changes allowing Members of the Scottish Parliament (MSPs) to more vocally oppose Ms Sturgeon's administration and has pledged to "get Scotland's economy moving".
Mr Sunak would force Scotland's top civil servant to appear before a committee of MPs at Westminster every year. Holyrood would also have to publish consistent data on the performance of public services.
Tonight's sold-out hustings event will take place in Perth, which is an eight-hour drive north from Westminster and home to a constituency where the Tories very narrowly trail the SNP.
Ms Truss has labelled Nicola Sturgeon, the First Minister, an "attention-seeker" and promised to "ignore" her, a move Mr Sunak claimed would be "dangerously complacent".
The Foreign Secretary, the clear front-runner in the race to become prime minister, received another boost today with endorsements from 11 party whips who had previously stayed neutral.
