Long A&E waits have improved slightly, the latest figures have shown.
The proportion of Scots waiting under the four-hour target rose from 64.2% to 65.6% in the week ending June 4.
Waits over eight hours decreased from 11.8% to 11.1%, while waits longer than 12 hours decreased by 0.4% to 4.4%.
The Scottish Conservatives accused First Minister John Swinney and Health Secretary Angela Constance of being “missing in action”.

Miles Briggs, the party’s health spokesman, added: “These miserable stats expose the SNP’s sheer incompetence in running our health service.
“We’re approaching the height of summer, but Scotland’s overcrowded A&E departments are under the kind of pressure we see at peak winter flu season.
“We know these lengthy waits lead to tragic and avoidable deaths, despite the best efforts of frontline staff.
“They are burnt out because they have been abandoned by successive SNP health secretaries who have been criminally out of their depth.
“John Swinney and his new health secretary, Angela Constance, should be urgently tackling this crisis, but they are missing in action.
“They should accept their approach isn’t working and back our common-sense plans to slash bureaucracy, cut red tape and ensure resources get to frontline care.”
Health Secretary Angela Constance said: “While there’s been some improvement in the past week, A&E departments continue to experience significant pressure.
“This is not unique to Scotland with other UK nations facing similar demands.
“I am committed to improving A&E performance and tackling delays for patients.
“That’s why we will be publishing a new national plan for improving the flow of patients through our hospitals, from the front door to discharge, within our first 100 days.”
