The government will provide funding of up to £20m each to 75 areas to spend on regenerating local features such as high streets, parks, youth clubs, cultural venues, libraries and health services.
The £1.5 billion Plan for Neighbourhoods is aimed at transforming "left behind" locations by improving local services and tackling issues such as crime.
Among the areas chosen are Scunthorpe in England, Irvine in Scotland, Wrexham in Wales, and Coleraine and Derry~Londonderry in Northern Ireland.
In each area, a new 'Neighbourhood Board' will bring together residents, local businesses, and grassroots campaigners to implement a new vision for their area and decide how to spend up to £20 million over 10 years. Example activities are repairs to pavements and high streets, setting up community grocers, running co-operatives and creating neighbourhood watch schemes.
The government has also published a list of regeneration powers that communities are encouraged to use, such as saving pubs by listing them as community assets, and using respect orders to tackle repeat offenders.
