Overview The election produced a large majority for Reform UK. Gaining seats across the county, and winning the popular vote by a wide margin, Reform UK made significant gains at the expense of both the Conservative and Labour groups. The Conservatives experienced an electoral collapse, losing over half their vote from 2021, losing two-thirds of their seats. Their leader, Barry Lewis, who had been leader of the council since 2017, lost his seat. The results were also punishing for Labour, losing eleven seats, and a significant portion of their vote from the previous election. They were wiped out in most districts by Reform UK and reduced to 3 seats, a record low for the party. The Labour leader, Joan Dixon, was defeated in her seat. The Green Party won an additional seat in Amber Valley, and the Liberal Democrats lost a seat to finish on 3 - joint third with Labour. Two Independents were also elected, including former High Peak MP,
Ruth George. Reform UK had no councillors on the county council prior to the election. After the election, the new Reform UK group chose Alan Graves to be their leader; he was already the Reform UK group leader on
Derby City Council. He was formally appointed as leader of the county council at the subsequent annual council meeting on 21 May 2025.
