The West Ham parliamentary constituency, like pretty much all of Newham, is in the London Travelcard Zone 3 and has good transport connections with much of London. To get to, say, Westminster one can take either the District Line (with three stations in the constituency - West Ham, Plaistow and Upton Park, though the latter is on the current constituency boundary) or the Jubilee Line (two stations - Stratford and West Ham), both with plenty of direct services. And that's to say nothing about the numerous interchange options involving tubes, trains, buses, the DLR and more. With the current row about MPs' expenses it should be the ideal constituency for someone to live in and commute to Parliament.
So why is Lyn Brown MP claiming £15,889 a year for a second home? (The Daily London News: What does your London MP earn and claim?) According to former councillor Mike Law she was living in Plaistow until at least recently. Tellingly her website is silent on this one.
So why does she need a second home? Where is she claiming from? What does she need it for?
