The SNP was given two sharp reminders yesterday of how quickly things can change in politics.
The party was comprehensively beaten by Labour in a North Lanarkshire council by-election despite a campaign visit from the First Minister. And another poll showed the SNP’s lead in Westminster voting intentions continues to narrow.
The same survey also revealed Nicola Sturgeon’s reputation as Scotland’s most popular politician is over. The former first minister’s net approval rating has dipped below zero for the first time.
