A highly personal vote after representing the constituency for over 4 decades, it's no real surprise that Corbyn retained. It's also extremely unlikely he will vote against Labour on the vast majority of the programme.
Compare that to Chingford, where Shaheen insisted on running as an independent after being deselected (fairly or not doesn't really matter), and having never actually won an election (let alone 40 years worth), and split the vote so much that the architect of food poverty in the UK, Iain Duncan Smith, managed to cling on to his seat.
Her ego got in the way of removing a proven sabateur from Parliament, that is unforgivable.
