Nicola Sturgeon will today urge Scots to vote for the SNP at next month's council elections "to send a message to Boris Johnson".
Voters go to the polls on May 5 to return councillors across the 32 local authorities in Scotland at a time of soaring inflation, rising fuel prices and a hike in National Insurance contributions.
Councils also face a £250 million spending gap next year which town hall bosses have warned will lead to cuts in services.
