The district councils opposed the single unitary Buckinghamshire plan, and considered legal action against it. For details of the inaugural elections to the new council, see 2021 Buckinghamshire Council election. The existing unitary authority of Milton Keynes was not affected; since 1 April 2020, the ceremonial county of Buckinghamshire has therefore been composed of two unitary authorities.
