The party will roll out advanced campaign software – which helped propel Barack Obama to power in the US – over the weekend, targeting seats where it believes it can beat the SNP.
Labour campaign chief James Kelly said: “These are areas where it is a two-horse race between Labour and the SNP, and voting Tory in these areas will just let the Nationalists back in.
“With postal ballots landing on doormats across Scotland, and polling day less than a fortnight away, voters are turning their minds to the election and they are increasingly fed up with Nicola Sturgeon’s record in office.”
The cutting-edge technology, inspired by successful electioneering from progressive parties in Europe and the Obama presidential campaign, uses socio-demographic modelling and polling to identify the key swing voters in each constituency.
Edinburgh South, East Lothian and East Renfrewshire are among the seats being targeted.
