The First Minister also criticised Scottish Conservative leader Ruth Davidson for attempting to "stir up division" over the constitution.
The Sun runs with the headline "Blue Labour", calling it a "bold bid" to win over socialist voters, and inside the paper says the choice between the Conservatives and Labour at the ballot box is a "no-brainer".
