There are a lot of "tankie" pro Corbyn Journalists working for the Guardian.
For those unfamiliar with British political discourse, the term "Tankie" is often used in British left-wing circles to refer to supporters of Stalin (including his approach to political change through violence), and is usually used in contradistinction from "Trots" (= follower of Leon Trotsky's -- who disagreed with Stalin on several things, but not on the use of violence). Whatever one might think of Corbyn and his supporters, "Tankie" is probably not as exact as might be desirable.

I think the "tankie" description is pretty fair when applied to likes of Seamus Milne and Andrew Murray, though of course Milne stopped being the Guardian's comment editor to work for Corbyn and Murray hasn't written for them since 2013.
A tankie is the sort that sells the papers with editorials praising Assad for crushing the counterrevolutiony scum beneath the wheels of tanks.
