Scottish Labour party members across the north and north-east are being given the opportunity to grill leadership candidates.
Hustings events are being held in Inverness on November 28 and in Aberdeen on December 1.
Jim Murphy, MP for East Renfrewshire and Lothians MSPs Neil Findlay and Sarah Boyack will try and persuade members why they should be given the top job at a time when opinion polls suggest the party could lose most of its 40 seats at the general election next May.
The audiences will also hear pitches from deputy leadership candidates Kezia Dugdale, a Lothains MSP, and Katy Clark, MP for North Ayrshire and Arran.
Both woman studied law at Aberdeen University.
Details of the venues will be announced by the party in due course.
In a statement to members, Scottish Labour said: “This is your party and its future is in your hands.
“That is why over the coming weeks we want to encourage every member to engage with the process so you can make your voice heard and that every candidate has the opportunity to make their case to you.”
The contest was triggered by the shock resignation of former leader Johann Lamont earlier this month, which prompted her deputy Anas Sarwar to also step down.
The Communication Workers Union, which represents 17,000 postal and telecommunication workers in Scotland, announced yesterday that it was backing Mr Findlay for leader and Ms Clark as his deputy.
CWU general secretary Billy Hayes said: “We need a leadership team in Scotland that can unite the party and take Labour to victory (in the general election) next May.
“We know Neil and Katy will be leaders who are committed to defending the rights of working people in Scotland and will work with trade unions to fight for social justice.”
Mr Findlay has already won the support of a number of trade unions including Unison, the GMB – Mr Murphy’s union – and Unite.
The former teacher, housing officer and brick layer, who was first elected to Holyrood in 2011, claims he is “not a career or a machine politician” but a ordinary man who is determined to tackle poverty and inequality.
Nominations for the post have closed and the new leader due to be announced on December 13.
