The leader of the Conservative group on Chorley Council has stepped down.
Coun Mark Perks made the decision after having several strokes last weekend.
He previously had a stroke in February and had been on the road to recovery, returning to council duties and attending meetings.
Coun Perks will continue as a councillor, representing Astley and Buckshaw on Chorley Council and Chorley North on Lancashire County Council.
Coun Paul Leadbetter, deputy leader of the Conservatives, has become the acting leader and will attend tonight’s full council meeting at Chorley Town Hall.
The Conservatives will hold a meeting on Monday when the party will select their next leader.
Coun Perks was appointed as leader of the Conservative group in June 2014, when Coun Greg Morgan stepped down from the role.
He has been a member of Chorley Council since 2002 and retained his seat in the local elections in May.
He has also been a county councillor since 2005, which covers Astley Village, Buckshaw Village, Euxton North, Clayton-le-Woods and Whittle-le-Woods.
