In a document today exposing Mr Corbyn's views on the Union, the Scottish Conservatives are highlighting how:
* Mr Corbyn thinks an immediate second referendum on independence is "absolutely fine"
* He didn't even bother campaigning in the 2014 independence referendum because he was "doing stuff" in London.
* He has talked up a pact with the SNP and Nicola Sturgeon - who he thinks is "brilliant" and "very effective".
* He has refused to call himself a Unionist - because it reminds him too much of the Conservative party
* He thinks that working together successfully with other pro-UK parties to win the 2014 referendum and save the Union was a "fundamental mistake" because it damaged Labour's brand.
It comes as Mr Corbyn prepares to travel to Aviemore tomorrow for the STUC conference. Nicola Sturgeon is also due to speak to the conference.
Scottish Conservative deputy leader Jackson Carlaw said
"The bottom line is simple - Jeremy Corbyn is a clear and present danger to the Union.
"This is a man who didn't even campaign in Scotland to fight for the Union in 2014 because he was 'doing stuff' in London.
"It's the same man who, since becoming leader, has talked up a pact with the SNP and just last month, said he was 'absolutely fine' with a second referendum.
"It all points to one clear fact: Mr Corbyn would sell pro-UK Scots down the river in a heart beat.
"Nicola Sturgeon is trying to use this election to push ever harder for a second referendum on independence. Under Jeremy Corbyn, Labour would simply roll over and let her do so.
"Therefore, the only effective way to stop the SNP in their tracks is to join the growing number of people in Scotland who will be voting for Ruth Davidson and the Scottish Conservatives."
