Scotland's accident and emergency waiting times have matched the highest level on record, according to news figures.
A Scottish Government target aims to ensure 95 per cent of those at A&E departments are seen and discharged or admitted within four hours.
Figures published today show that just 66.2 per cent in the week up to April 10, matching the previous low level recorded in the week up to March 20.
Public Health Scotland states reveal that 7,705 of the 22,774 people who attended A&E waited more than four hours.
Meanwhile, 2,373 people waited more than eight hours and 944 were in hospital for longer than 12 hours.
Opposition parties slammed the SNP government for its record on A&E waiting times.
Scottish Labour health spokeswoman Jackie Baillie said: "Barely a week goes by without performance falling to record lows somewhere in our NHS.
"A&E services have been in critical condition for months now, but the SNP have failed to act.
"Heroic NHS staff are working tirelessly to keep things running and keep patients safe, but there is only so much that can be done to paper over the cracks of SNP failure.
"Lives are at stake here - we cannot let this chaos become the new normal in our emergency rooms.
"The SNP must act now to support A&E services and tackle problems like delayed discharge, which are piling pressure on to services."
Scottish Tory health spokesman Dr Sandesh Gulhane said the figures showed emergency care required "immediate action from the Health Secretary".
"I fear we'll get the now familiar sound of silence from Humza Yousaf," he said.
"It's completely unacceptable that more than one-third of patients are having to wait over four hours to be seen, because these excess delays lead, tragically, to avoidable deaths.
"We're past the recent peak of Covid infections, so the number of NHS staff absences ought to be easing.
"The problem is that the SNP government's appalling workforce planning means there is no slack in the system, and so there are staff shortages across Scotland's NHS and, especially, in our emergency wards.
"A&E, like our health service generally, is on its knees and yet the SNP's only solution for the crisis is the Health Secretary's flimsy Covid Recovery Plan, which simply isn't cutting it. Patients and shattered staff deserve so much better."
Scottish Lib Dem leader Alex Cole-Hamilton urged the Scottish Government to "set aside" work on another independence referendum - with some civil servants devising a new prospectus for an independent Scotland - and repeated calls for an inquiry to be held into the state of emergency care.
A spokeswoman for the Scottish Government said: "The Covid-19 pandemic continues to put pressure on hospitals and this week's performance against the four-hour A&E measure was 66.2%.
"However, the figure is likely to be an undercount and direct weekly comparisons are difficult as NHS Highland was unable to submit complete data due to a technical issue.
"We continue to see high levels of Covid transmission and people in our hospitals with the virus, but there are some indications that numbers are stabilising.
"Hospitals face capacity issues as a result of high demand and staff absence while the high number of patients presenting acutely unwell is leading to longer stays."
She added: "NHS staff have worked incredibly hard during the pandemic and they have our thanks for the care they continue to provide the people of Scotland.
"Today the Scottish Government has announced that health boards have recruited more than 1,000 additional healthcare support staff and almost 200 registered nurses from overseas to help address the unprecedented challenges facing health services. Arrangements are in place to recruit a further 203 overseas nurses."
