The Prime Minister has vowed to take power out of Westminster and give it to local leaders, allowing them to improve public transport, build homes, and create jobs in their communities.
According to the Prime Minister, this policy will give local leaders more resources to address their specific needs, with a larger share of taxes raised in a community staying within that community.
The plan involves devolving tax revenues to mayors, who will have the power and resources to implement policies tailored to their local areas.
Large swathes of England already have mayors in charge, including Greater Manchester, the Liverpool City Region, Cambridgeshire and Peterborough, and South Yorkshire.
Other regions will soon elect new mayors for the first time, including Greater Essex and Hampshire and the Solent.
The Chancellor has stated that local leaders are best equipped to understand the needs of their communities and make decisions that benefit their area.
The Conservative Party has expressed skepticism about the plan, warning that it would lead to higher taxes and could not be imposed from above.
The Lib Dems have also raised concerns, arguing that devolving tax revenues to mayors would leave behind large swathes of England that do not have a mayoral authority.
The plans are set to be unveiled in more detail in the December budget by the Chancellor.
A key goal of the policy is to bring power and resources closer to the people who need them most, with the Prime Minister stating that this is how they will "bring back hope" and "bring power home".
