Doesn't it make sense, with 4.5 million people in housing need, to boost supply? Surely those in need and on low incomes should not expect to be housed centrally anyway (the myth-makers like to refer to 'Mayfair' or 'near Harrods' as if these neighbourhoods of the global mega-rich are stuffed with council estates). Well, no, it doesn't make sense. Because behind the beguiling simplicity of the idea lie some complex realities, and as an MP for North Westminster, and previously for the much-cited example of Notting Hill, I have some knowledge of these.
