Throughout July and August all eyes will be on London. Whether it is the unveiling of the Shard or the opening ceremony of the Olympic Games, London is demanding the attention of the nation. It is therefore no surprise that last week’s announcement of new powers for England’s eight cities was met with little fanfare. Yet, these "City Deals" represent the most significant devolution of power from Whitehall in decades and are deserving of more attention. This is not just the summer of the capital; it is very much the summer of the cities.

England’s eight core cities and their surrounding areas are forecast to add £71bn to the economy over the next decade. But evidence suggests that they have the potential to achieve much more. That is why the City Deals, that include transport infrastructure funds, new investment for SMEs, and apprentice hubs to support NEETs, will play a crucial role in the nation’s future growth.

The first clear indication of a new relationship between central government and England’s cities was the creation of a Minister for Cities last year. Greg Clark was appointed to this role, with further support from Nick Clegg and ministers and officials in BIS, CLG and HMT. The Deals are the result of an almost year-long negotiation between Clark and his team in the Cabinet Office, Whitehall and the core cities.

Arguably of most significance are the new transport infrastructure funds. They have a combined value of over £5bn and should have significant impact on the ground. Transport has been the policy area that the Mayor of London has had most influence over; the congestion charge, tube upgrades, a bicycle hire scheme and even a cable car over the Thames, have been the result. Getting around the capital is now easier and the same could soon be true for England’s core city-regions.

Better connections will support economic growth. Leeds City Region, for example, hopes that its £1bn West Yorkshire "‘plus" Transport Fund will create a 2 per cent increase in the region’s economic output and 20,000 extra jobs. Strategic investment in new stations, roads and public transport networks could have a dramatic impact on the daily commute.

People’s daily lives and commutes do not reflect arbitrary council boundaries, so another positive to have emerged from the Deals has been councils which are increasingly willing to work together to make investments. Greater Manchester’s councils combined strategy for a new Metrolink is a demonstration of the benefits of this approach. Such collaborative governance arrangements will prevent the jam-spreading of funds that can harm local areas.

The next step for the core cities will be to ensure they deliver on the ground. There is more work for central government to do as well. Greg Clark has said that this is just round one of City Deals. 142 upper-tier councils don’t have a Deal. A devolution bill could package up some of the powers in the City Deals allowing all areas to invest for local growth.
