Derbyshire County Council's deputy leader has suffered a heart attack, it has emerged.
A well-placed source said Councillor Simon Spencer suffered the 'major' medical emergency at County Hall in Matlock last week.
He was resuscitated by life-saving members of staff who have been left 'really shocked'.
It is understood Coun Spencer had three stents fitted and may need an internal defibrillator.
Council workers along with Conservative, Labour and Liberal Democrat councillors have wished him a speedy recovery.
Coun Barry Lewis, leader of the Conservative-run authority, said Coun Spencer's work was being managed by himself and four other colleagues in his absence.
"We'll know more about Simon's recovery plan after next week," he added.
"It really does put things into perspective."
As well as being deputy leader, Conservative Coun Spencer represents the Dovedale division on the county council.
This ward covers Ashbourne north, Compton, Elton, Monyash, Taddington, Tideswell and Youlgreave.
