Labour proceeds at its own peril. Kicking out Ken Livingstone didn't work the last time. Outside of the media echo chamber, his comments are perfectly inoffensive (albeit probably wrong).
If Corbyn fails or retires, Livingstone is now perfectly positioned to engage in a hostile takeover of an increasingly Muslim Labour.
What? Ken has as much chance as Dianne Abbott (see 2015 mayoral primary)
If you want to win a Labour leadership race you need to win London, which is largely made up of white public sector workers (in my own experience of the party)
