Local Government Association chairman Sandy Bruce-Lockhart said:
'In England, too many powers are held centrally or fragmented among a set of non-elected bodies which includes regional development agencies, regional housing and planning boards, learning and skills councils.
'On the continent, cities such as Frankfurt, Milan and Madrid have higher, faster growth compared to equivalent cities in Britain.
'With greater devolution on taxation and clear powers over transport, infrastructure, planning, economic development and skills, they have managed to develop local economies with an inbuilt and self-generated dynamism that benefits not just the city, but pulls up the whole region.
'London's economic success is further evidence of the importance of devolved powers.
'It is local council Leaders working on the ground in their localities who can win the public's backing for economic and social initiatives. They are the people who can form strong partnerships with the private and business sector, and work with wealth and social capital creators to deliver major physical improvements and stronger local economies. But this can only happen if they have the devolved powers to do so, particularly in planning, transport and the economy.'
'Whitehall should learn from their experience and give these powers to all English cities.'
