SCOTTISH Tory leader Douglas Ross has "shown his lack of experience" according to the SNP as he urged other Holyrood parties to back votes of no confidence in First Minister Nicola Sturgeon and her deputy.

The Moray MP challenged Scottish Labour, LibDems and the Greens to “show that they have the stomach to stand up to this SNP Government” in an online speech to the think tank Onward today.

His party are looking to bring the motions of no confidence against Sturgeon and Deputy First Minister John Swinney in the wake of the Scottish Government's mishandling of complaints made against former First Minister Alex Salmond.

The Tories are hoping to hold a vote against Swinney on Tuesday or Wednesday due to the delayed release of legal advice to the Scottish Government by the Deputy First Minister.

The party has not set a date for a motion against the First Minister.

Ross said Labour, the Liberal Democrats and Greens should “unite with us and stand up for the Scottish Parliament and its fundamental principles”.

The Tory leader also called for reform to the Scottish Parliament which he said is "increasingly dated in its 1999 model of operating".

SNP depute leader Keith Brown said Ross and his party were trying to "erode confidence in our democracy", adding that Scots want the Government to focus on recovering from coronavirus.

Brown said: “All Douglas Ross achieved with such blatantly transparent tactics was to highlight his own inexperience and lack of political nous.

“The Tories have always hated devolution and fought tooth and nail to stop our nation’s parliament being established.

“Now, they’re doing everything they can to try to erode confidence in our democracy brick by brick from the inside – no one will trust the Tories to protect Scotland’s Parliament.”
