London’s next mayor must be unashamedly in favour of airport and housing expansion

I feel sorry for the Conservatives’ London mayoral candidates. With the political landscape transformed by the election of a “pre-1970s socialist” to the Labour leadership, voting in the current Tory primary feels a bit “after the Lord Mayor’s Show”.
In such a centralised country, regional politics will always play second fiddle to stories about what the Prime Minister did at university. But the mayoralty can shape important policies. Housing and airport capacity are obviously the most acute issues to be dealt with.
But the ability to utilise the bully-pulpit to represent the capital’s interests on immigration and the City of London, whether in or out of the EU, should not be underestimated. How do the candidates perform?
The posters of three of the candidates (Andrew Boff, Stephen Greenhalgh and Syed Kamall) outline housing as a key priority. Zac Goldsmith’s poster only highlights his ability to win.
London’s housing problems are, at root, about land. With demand ever-rising due to higher incomes and population growth, the operation of a market would naturally see London expand – either outwards or upwards. Yet it can’t, because it is fenced in by large tracts of “green belt” and regulations on building heights in certain areas too. This creates structurally very high house prices and rents.
I haven’t seen any of the candidates take on the green belt shibboleth – perhaps unsurprisingly, given the ferocity of NIMBYism. But at least Kamall, Boff and Greenhalgh acknowledge land availability is extremely important.
Their stated focus on releasing public sector land, however, while useful, is a red herring. Yes, it could help meet need for two to three years, but given population growth, land-use reform more generally – including the green belt – is essential for the long term.
It seems from what Kamall says that he is closest to understanding this, and the need for more fiscal decentralisation to allow boroughs to gain from development. Goldsmith’s emphasis on brownfield sites, in contrast, is simply a dead end. Decontamination costs on these sites are often high, making the process long or uneconomic.
Some of the candidates’ policies would actually worsen the situation. Goldsmith has jumped on the bandwagon of arguing for “longer tenancies” and “more certainty over rent increases” – as if landlords are to blame for structural problems in the market.
This helps nobody, and legitimises demands for rent control, depressing investment without improving affordability. Boff, meanwhile, wants to restrict new residential developments in all but five areas to just six storeys – another constraint which will merely prevent supply from meeting new demand.
The dividing lines on airport capacity are clearer. London desperately needs new capacity, but it would be preferable if where this occurs is decided by market processes rather than political decrees. Greenhalgh and Boff simply state the need for a (high risk) Thames Estuary airport.
But clearly the market is signalling a demand for Heathrow expansion right now. While there’s no doubt this comes with noise and environmental costs – which leads to Goldsmith opposing any expansion – economists have long thought of ways to deal with these “externalities”.
Though Kamall is the only candidate who hasn’t ruled out Heathrow, his idea of a London-wide referendum to decide where new capacity occurs could throw up difficulties.
Why should Londoners decide where the new runway goes, when many in London aren’t affected directly by Heathrow and other parts of the population are affected by the decision too?
If I were advising him, I’d suggest revising his referendum to make it highly local for those directly affected by noise. The airport could tailor a compensation package, and this package could be put to a referendum of those affected, with changes made until the residents were satisfied with the deal.
This would see the airport bear the costs of the externalities, and depoliticise airport expansion entirely.
In short, London needs a mayor who will be unashamedly in favour of expansion to meet demands – whether in housing or airport capacity.
