Devolution and local government reorganisation (LGR)

Sussex will be one of the first areas in England to elect a new mayor and secure greater decision-making powers as part of the government's devolution priority programme agreed for a number of different areas of the country.

In December 2024, the government published the English Devolution White Paper. This sets out plans to move power out of Westminster and back to local communities, allowing for tailored solutions that address specific regional needs, such as on transport, housing, education and economic development.

The government has now agreed to move forward with a Mayoral Combined County Authority (MCCA) and confirmed the first mayoral election will take place in May 2026.

As part of the devolution programme, local government will be reorganised by replacing two-tier systems (county and district councils) with single-tier unitary authorities.

What are the next steps?

All West Sussex county, borough and district councils have been working together to develop a business case for local government reorganisation (LGR) that has now been submitted to the government.

The business case was informed by public feedback from the Shaping West Sussex survey which engaged residents, stakeholders, members and staff on three unitary model options that were identified as viable.

It presents a shared evidence base for all councils but does not recommend a single preferred option. It is for individual councils to consider the full range of evidence and analysis presented in the business case and determine their own stated preference for submission to the secretary of state.

We have included a supplementary statement that explains the recommendation for a two-unitary model that combines the Adur, Arun, Chichester and Worthing footprints.

To read the business case, see:

Now that the business case has been submitted, the government will undertake consultation. A final decision from the government is anticipated in Spring 2026. New unitary authorities in Sussex are set to go live in 2028.

Thriving Together

At Adur & Worthing Councils, we want to go further. This isn't just about councils getting more powers - it's about ensuring that our communities and partners have a real say in shaping the future of the places we live, work or study.

We believe that devolution and LGR should reflect what makes our places special - our people, our creativity, and the unique strengths of Adur and Worthing. That's why we have been inviting residents, local organisations, businesses, and public sector partners to join the conversation.

This is an opportunity to think beyond council structures and focus on what our places need - whether it's enabling communities to support each other, developing thriving local economies, or tackling the big challenges together.
