Previously, the party had supported an income tax cut to help struggling families and put cash in the pockets of those who needed it the most.
But last night, the party leader backtracked and confirmed they’d be seriously looking at raising income tax.
Speaking on Scotland Tonight Willie Rennie said: “That’s something we’re seriously considering because of the hammer blow the SNP are going to deal to the education sector in Scotland, we need to seriously look at getting Scotland fit for the future.”
He added: “We’re seriously going to look at it. It’s going to be modest, it’s going to be reasonable and it is going to be costed.”
The Scottish Conservatives are the only party committed to not increasing income tax when those powers come to Holyrood through the Scotland Bill.
Scottish Conservative deputy leader Jackson Carlaw said:
"Many people who formerly voted LibDem in the belief they were a moderate force on tax will be rightly dismayed by Willie Rennie's comments. “There is no reason why people in Scotland should pay more in tax than people elsewhere in the UK. Yet Mr Rennie is now preparing to join Jeremy Corbyn on the left by advocating a fresh raid on pay packets. It isn't fair or justified.
"It's also yet another LibDem flip flop. At the last Holyrood election, the Lib Dems were proposing an income tax cut. Now Mr Rennie is proposing the exact opposite.
"It only goes to show that when it comes to family finances and Scotland's security, the only party you can trust to stick by its principles is the Scottish Conservatives.
