Humza Yousaf's plan to achieve a second referendum on independence is a "big risk" for the SNP as it faces a revived Labour, a top pollster has said.
The First Minister announced on Saturday he would have a mandate to demand an IndyRef2 from the UK Government if his party won the most seats in Scotland at the next general election, which is expected next year.
Yousaf said his intention would then be to a call a referendum as soon as possible afterwards.
