Local authorities in Wales have been urged to use their existing powers and resources to make town centres sustainable.
A new report from Wales' auditor general found that one in seven shops on Welsh high streets are empty due to past policy choices, changing consumer expectations, technological advances and COVID-19.
Auditor general Adrian Crompton stressed that local authorities were key due to their wide range of statutory powers, which can determine the shape and environment of town centres.
Mr Crompton said: 'National and local government need to deliver integrated solutions, make brave decisions and provide bold, ambitious leadership if we are to address the challenges facing our town centres.'
