In the Scottish election on 3 May 2007, she failed in her bid to win the Hamilton South constituency, being defeated by Labour's Tom McCabe. However, she was elected as a regional member for the Central Scotland region. She was appointed deputy Scottish Conservative Spokeswoman on Justice, until 2007 when she became Convenor of the Parliament's Equal Opportunities Committee,^[1] a role which she held until 2011 after which Mitchell was appointed as the Scottish Conservative Local Government Spokesperson.

On 17 April 2020, Mitchell announced that she would be stepping down from Holyrood at the 2021 Scottish Parliament election. "By the end of this session in 2021 I will have had the privilege of representing my Central Scotland constituents for 18 years and I thank you all for your support," she said. "However at the end of last year I made the huge decision that, having achieved most of the things I set out to do, I would not seek re-election in 2021. In doing so I am re-assured that I leave my party's representation both at local government and parliamentary level in a much better place.^[4]
