Labour's only MP in Scotland has said his colleagues should look at creating a separate party north of the border as an option.
Ian Murray, who has not backed the idea himself, nonetheless said that every idea for reform should be considered.
Scottish Labour lost six of its seven seats at the general election and recorded their worst result since before the second world war.
The electoral humiliation triggered a bout of soul searching and led to senior politicians making calls for far-reaching changes.
Monica Lennon, the party’s shadow health secretary, wrote last week that Scottish Labour should breakaway and become separate.
Her call was fuelled by anger at the way UK Labour softened the party’s opposition to independence without consulting Scottish colleagues.
She wrote in the Daily Record that it was no longer tenable for decisions about Scottish Labour to be "taken or undermined by colleagues outside Scotland", and warned: "If we look like a pressure group within a UK party structure, we will continue to be rejected."
She added: "Scottish Labour needs to stand or fall by its own decisions. We either continue at the mercy of the UK party's distant structures or we become a party in our own right.
"This would mean raising our own funds, persuading trade unions to affiliate and reaching out to voters and organisations in a more meaningful way.”
In a television interview, Murray, a leading moderate who is standing to become his UK Labour’s deputy leader, cautioned against “knee jerk” reactions after the election defeat.
However, he said of the separate party call: “Maybe we should look at that as an option. Leave everything on the table.”
Murray also said it was important to focus on external, not internal, matters.
