Tomorrow, Boris Johnson, publishes his long-awaited "vision", setting out what he wants to achieve for London by 2020. (That 2020 would be the year a third Johnson term would end is no doubt a complete coincidence.)
This is an important moment in Boris’s mayoralty. He came to the job having run nothing larger than a small weekly magazine – the Spectator – and with a good Tory wariness of anything that smelled of bureaucracy, including the long tiresome strategic documents which bureaucracies are wont to produce.
As a result, Boris left the GLA’s strategic framework more or less as he found it. He revised those strategies he had to revise and overhauled London government architecture by, for instance, abolishing the London Development Agency. But his first term was unmarked by any fundamental recasting of the GLA’s aims and objectives or a sharpening of its strategic capability.
What Boris brings to the mayoralty is personal charm bordering on charisma - no small quality in a political leader, especially one in a position where most of the power is of the 'soft' kind. Boris is good at persuading government leaders and businesses of the merits of investing in the London, and tells the city’s story well to the rest of the world. Clement Attlee is meant to have said that Churchill won the Second World War "by talking about it". Boris has led London in much the same way - lots of talking but not much strategising.
After his second election, however, Boris made an apparently off-the-cuff commitment to his GLA staff to produce a vision for London - something that would provide a point of unity around which everyone working for him could unite. Six months after it was due to be published , the big day is fast approaching. Rumour has it that it’s a 'personal document', written in Boris’s voice.
We can predict with confidence some of the things that will be in it. Almost certainly, it will call for devolution of finances to London, as set out in the final report of the London Finance Commission . It will reiterate Boris’s opposition to any expansion of Heathrow and call for a new hub airport in the Thames Estuary. It will argue for more funding for homes and transport, in light of London’s higher than predicted population growth – it’s no chance that it is being published in the run-up to the announcement of George Osborne’s Spending Review on 26 June.
But what about the things that it should include but might not? I set out three below.
First, we at Centre for London will be looking for a stronger narrative than Boris has yet produced about London. For all of his eloquence, the Mayor has oddly failed to offer a compelling account about the city he wants to London to be. For a while he talked about "creating a village in the city". He talks about maintaining London’s competitiveness and its position as a leading world city and, more wittily, of London as the centre of a new "BRIC-ish Empire." But he has never come up with a story that has really stuck.
Boris has to develop that story for himself – it needs to be personal. But its starting point has got to be that London’s future lies in it retaining and building on its status as a global city. London is never going to compete on being cheapest city in the world but it can compete, and win, as the most innovative and creative one, a competitive place for high value businesses, and a city that offers offers a great quality of life and opportunity for all its inhabitants. Charlie Leadbeater  put this well at last year’s London Conference  when he developed the argument that London’s future lay in it being at one and the same time a "high-system" city, with an efficient transport system, decent homes, safe streets and highly professional public services, and a "high-empathy" city – one where people from different backgrounds connect, where friends are easily found and kept and with a rich and engaging public realm.
Second, the 2020 vision has to mount a convincing argument in favour of London winning more power to govern itself. The coalition government sees itself as a decentralising one and has gone some way to devolving control to London (notably over housing and, to a lesser degree, policing) and other cities. But as the London Finance Commission noted, England remains an extraordinarily centralised country by international standards and while decentralising control over taxation from central government to the capital, as the Finance Commission recommended, would be a huge step forward, there is further to go. London government is better positioned than central government to tailor policies to local circumstances and join up services. There is a good argument for devolving housing benefit budgets to the GLA, and devolving spending on skills and training from Whitehall to London boroughs,who understand local economic needs and opportunities and are well positioned to connect employers and businesses. Ideally, Boris’s document should include a commitment to work with England’s other cities to help win the argument for devolution and make a success of it.
Finally, the 2020 vision should include prominent affirmation that London is not just a world city but a capital city too . London is already viewed as greedy and arrogant by much of the country and its continued economic growth, relative to the rest of the UK, is bound to put a further strain on relations. It’s not enough to argue, as London’s leaders tend to do, that the capital’s prosperity trickles down to the rest country, or that 'what’s good for London is good for the UK'. Of course the Mayor needs to continue to make the case for London but he also needs to acknowledge national reservations about London’s dominance, and the widely-held view that it is favoured by Whitehall and Westminster. The 2020 vision should launch a conversation about how London can do more to help the rest of the UK. For a politician of national ambition, Boris shows surprisingly little interest in building relations with the other regions and cities of the UK.
We shall discover on Tuesday whether the nine months' work that Boris has put into his 'vision' marks a big step forward in his thinking or whether it will be business as usual at the GLA.
