Labour bosses have pledged to hold a public “listening exercise” in the wake of last week’s dismal election result which left the party with only one MP in Scotland.
Scottish Labour leader Richard Leonard said the party would be conducting a “swift evidence-based review” to understand the loss.
The comments came as the party’s deputy Scottish leader, Lesley Laird, announced she would be resigning from the role.
Ms Laird, who lost her Kirkcaldy and Cowdenbeath Westminster seat to the SNP in last week’s election, used her resignation letter to take a swipe at colleagues who she accused of “destabilising” the party.
Ms Laird called for a period of “calm and kindness”, before adding: “Sadly there is now a culture where for some people in our party washing our differences in public via the media has become a far too regular self promotional or destabilising tool.
“It’s a behaviour that upsets our members and undermines all the good work our staff and activists do.”
Mr Leonard, speaking yesterday, tried to strike a more conciliatory tone.
He said: “After Thursday’s devastating election result, it is crucial that we learn the lessons of our defeat.
“We owe this to Scotland’s communities, workplaces and most vulnerable people, who are now facing the prospect of five years more years of Tory Government.
“In the coming weeks, we will be conducting a swift evidence-based review of the election campaign and result in order to chart our way forward.
“We will lead a public engagement campaign to establish why voters, who are clearly still desperate for change, no longer feel that Scottish Labour is the vehicle for the realisation of that change.”
The party must develop a “clear constitutional offer” that wins back the confidence of voters, Mr Leonard said.
The comments came as shadow transport secretary Andy McDonald appeared unapologetic for the party’s performance at a UK level.
Mr McDonald blamed broadcasters such as the BBC for allowing Jeremy Corbyn to be “demonised and vilified” during the election campaign.
Insisting the Labour manifesto and position on Brexit had gone down well with voters, Mr McDonald said he had “never, ever seen such a stacked deck in British politics”.
