A Labour motion which could see all ministers compelled to resign if it passes will be voted on at Holyrood.
A motion of no confidence in the Scottish government is due to be debated later on Wednesday.
Scottish Labour will press ahead with a vote of no confidence in Humza Yousaf’s Government.
Sarwar said Labour would "take an election tomorrow" as his party called for Scots to be given the choice to elect a new government.
The move comes a day after Humza Yousaf announced his resignation as First Minister.
