Frank Field has been elected as Labour MP for Birkenhead for 40 years and has been in the party longer than Corbyn.
He is left Wing, though not Far Left.
Like the Labour Blairites he is Centre Left, just as you claim to be.
Whatever your history you now show nothing but contempt for such politicians, and support the Far Left.
Name a Centre politician you approve of.
Name one you think too far Left.
