In January 2025, following a vote by Wiltshire Council, the leaders of Dorset, Somerset and Wiltshire councils said they had written to the UK government to show support for devolution of powers to the proposed combined authority.
This was despite reservations among Wiltshire councillors who felt that a mayor was "not right for a large rural area".
The three leaders said they remained open to discussions with the councils of Bournemouth, Christchurch and Poole (BCP), Swindon and North Somerset.
