The SNP's Westminster leader has called on the prime minister to "do the decent thing and resign".
It follows two of Sir Keir Starmer's top colleagues quitting Number 10 in less than 24 hours.
Responding to this, Stephen Flynn has said in a statement: "The Labour government is in chaos and completely distracted from the issues that matter – like helping families with the cost of living, which has soared under Keir Starmer."
He added that Labour has "lurched from one crisis to another and has failed to deliver the change voters were promised".
He continued: "It's not in Scotland's interests – or anyone's interests – for this chaos to continue endlessly.
"It's clear voters have lost confidence in Keir Starmer and, with his own MPs calling for him to go, he has become a lame duck leader who lacks the authority needed to deliver change.
"This never-ending chaos can't go on. Keir Starmer should do the decent thing and resign."
Earlier today, Conservative Party leader Kemi Badenoch warned the resignation of Tim Allan this morning shows Starmer "is in office, not in power" and has "lost control of his government".
Meanwhile, her colleague, Matt Vickers, suggested it shows "the rats are abandoning the sinking ship that is Keir Starmer's premiership".
But moments ago, the prime minister's spokesperson insisted Starmer will not resign today - and said he both has the confidence of his cabinet and is "upbeat and confident".
