This week, it’s the second in our mayoral walks mini-series.  Sian Berry is the co-leader of the Green party, a member of the London Assembly, and is currently running as the party’s candidate to be mayor of the capital for the third time. A few weeks before Christmas, we spent a gloriously crisp winter afternoon together walking from Manor House station to Dalston together, a route chosen mostly because it took us along Green Lanes (geddit?).  Along the way we talked about, among other things, air pollution, and how to fix it; how London can reform regeneration schemes so that they don’t screw over existing residents; and, something which Sian still has personal experience of, the capital’s private rental sector. We also ended our walk at a community “parklet” – a parking space, converted into a teeny, tiny park – and talked about how to take back space from cars. My next walk, all being well, will take place later this month, and will be with the man who inspired the whole project, Rory Stewart.
