Show Hide image UK 16 June 2015 Five things we learnt from the Labour London Mayoral hustings Labour’s candidates for London mayor had their first hustings. What did they reveal? Print HTML Open season It was open season on Ed Miliband, with one of the first topics being the mansion tax. In what ended up being a sort of top-down Two Minutes Hate about the divisive policy, the candidates revealed how they approach the Miliband era in general. Diane Abbott emphasised that she had always been a critic, and independent-minded, adding: “The people at the top of the party who promoted it didn't really understand London”. Tessa Jowell subtly stuck the knife in, saying the tax was “in effect, a three bedroom terraced house tax”. In contrast, Sadiq Khan defended the principle of the “broadest shoulders carrying the heaviest burden”. But it was later when the candidates were discussing airport expansion that the harshest condemnation of the former Labour leader sprang up. David Lammy, criticising Khan’s changing stance on the idea of a third Heathrow runway, bellowed: “Don’t play the same Ed Miliband politics that got us nowhere”. You and whose powers? One particular frustration with the mayoral selection is the temptation to propose policies that are not in the London mayor’s remit. When asked if they would like City Hall powers broadened, all the panellists reeled off a wish list of the things they’d like to control – from income tax to school places. But they neglected to say how they would wrest these powers from the Tory government, or even campaign for them. Jowell and political outsider Christian Wolmar were the most convincing in this area. Both repeatedly brought the debate back to what the London mayor can actually control. Jowell insisted on “realistic” housing targets, by starting off building on land owned by the mayor (which equals the size of Camden). And Wolmar directly referred to the role’s limitations on land value tax and rent capping – “we can bat for it but unfortunately we have a Tory government which won’t enable it” – and airport expansion (“oddly enough this isn’t a mayoral function!”). Global race Where Khan shone was on the global context of being a city mayor. He had clearly done his research on what powers mayors around the world have, and how they use them, from the New York mayor Bill de Blasio’s tech talent academy to the Stuttgart mayor’s business partnerships, with stop and frisk powers and everything else in between. As London differs wildly from the rest of the country, couching it in an international context adds weight to calls for devolution to the capital. Devolution is at the heart of Gareth Thomas's pitch, but all candidates are passionate about London receiving more powers, with Jowell being particularly strong on the practical benefits of devolving power both to City Hall and out to the boroughs. Election over selection The Jowell camp sees her ultimate trump card as her ability to win the election against the Tory candidate next May. “This selection is about who can win,” a sympathiser puts it simply. Indeed, a YouGov poll recently put Jowell +3 among Tory London voters. Plus her record in leafy Dulwich & West Norwood, and focus throughout the general election campaign on having a broad appeal (she told me ahead of May “my best way to spend a Sunday afternoon is talking to Tories”), make her the candidate most likely to pick up non-Labour voters. Wolmar did a bit of this, saying he had the policies to take on Zac Goldsmith (if not his “looks or his money”) – and as a non-politician, could reach non-Labour voters. Thomas too highlighted his record of consistently beating the Tories to his outer London seat of Harrow. There are concerns that rhetoric about the election, not the selection, is uncomradely. For example, there's been some muttering among the Labour ranks over an email recently sent out by Jowell’s campaign team directly referring to Khan following the YouGov poll (“Tessa beats the Tories, but Sadiq doesn’t” is its subject line). “If you’re the frontrunner, you shouldn’t mention your opponent; just glide over it,” one Labour source says. Fasten your greenbelts In spite of the debate focusing on the need to build more housing, the only candidate in favour of building on the greenbelt is Lammy. This was popular with the audience, but is it impossible for the other candidates to inch anywhere near the greenbelt for fear of losing voters in boroughs further out? › Trevor Phillips calls on Labour MPs to nominate Stella Creasy for the deputy leadership Anoosh Chakelian is deputy web editor at the New Statesman.
