The SNP group on North Ayrshire Council has given up control of the authority after a by-election defeat.
Labour became the largest party on the council last week after taking a seat from the SNP.
The losing SNP candidate was first minister Nicola Sturgeon’s father, Robin.
The first minister’s mother, Joan, has now stood down as Provost after the SNP resigned from the administration.
The decision paves the way for Labour to try and form an administration.
