The Cornwall Council member responsible for health and adult care has resigned from her position in a surprise move.
Judith Haycock stood down from the job but will remain as Independent member for Helston South.
Mrs Haycock said the decision to leave the cabinet position was entirely hers and no pressure had been put upon her to stand down.
Cornwall Council announced Penzance councillor Jim McKenna would be taking over the role.
The councillor was handed the post nearly 12 months ago following the Cornwall Council elections in May 2013.
She said: “I’ve just found over the months that there is an enormous quantity of work.

John Pollard said of the new appointment: “I am very pleased to welcome Jim to the Cabinet. He has done an excellent job in chairing the Health and Social Care Scrutiny Committee over the past twelve months.“
“I would also like to take this opportunity to thank Judith for everything she has done. Judith worked hard to develop the care and support we provide for adults in Cornwall. She has also brought her good judgement and a thoughtful approach to
Mr McKenna said: “I am delighted to have been appointed as the cabinet member for health and adult care. I am really looking forward to taking on what is a very challenging role."
