In chess, the King is rarely attacked directly. The usual method is to remove his guard, the pieces which surround him [see, for example, The Art of the Middle Game by Keres and Kotov, first published 1964]. In politics, the same sometimes happens. The figure attacked is not easily dislodged directly, so is subjected to indirect attack.
The Jew-Zionists want to remove Jeremy Corbyn, mainly because they say that they see his leadership of the Labour Party as facilitating “anti-Semitism” in Labour and beyond. The reality is more that the Zionists have influenced all major System parties in the UK since the late 1940s (and to some extent since the 1930s), and have had a stranglehold over British political life and parties since, at latest, 1989. They have become accustomed to having most MPs as their doormats. They want to, once again, fully control both major System parties.
Corbyn was never expected to win the Labour leadership and only got on the ballot via the “Hand of God”, meaning that MPs who did not support him and did not later vote for him yet nominated him! I still find that extraordinary. He needed 35 nominations and got 35 (36 including his own vote):

Corbyn’s position is unassailable if he stands firm against the almost hysterical Jew-Zionist “claque” noise now being howled at him and Labour. The Labour members and supporters mostly support him. Against him is the Jewish lobby: msm (Press, radio, TV), and the pro-Zionist anti-Corbyn MPs in Labour (maybe as many as 200 out of 258). So the “lobby” tries a different tactic, one that they have tried several times since Corbyn was elected Labour leader: to remove his guard, and then to checkmate him.
Thus we see attempts to rig Labour’s National Executive Committee (NEC) against Corbyn, to place on it pro-Israel persons, whether those who make a living from being pro-Israel (eg Luke Akehurst) or oddities such as freak Eddie Izzard.
Now “they” have, in poker language, “upped the ante” by prevailing upon quite pro-Jewish John McDonnell, Shadow Chancellor, “suited thug”, ex(?)-IRA supporter and sinister “antifascist” idiot, to pressure Corbyn. McDonnell is ambitious, sees himself as Corbyn’s successor and may want to stab Corbyn in the back. Labour is quite high in the polls. Any early general election (this year or in 2019) might well see Labour as the largest party and at least able to form a minority government. McDonnell may see himself as the next Prime Minister, incredibly.
Corbyn himself is prone to offering the Jews weasel words. That is because his risible old-style socialist worldview (including belief in the “holocaust” narrative fakery, “antifascism”, “The Battle of Cable Street” semi-history, “!No Pasaran” etc) is a huge part of the ideological baggage that he cannot jettison. Cognitive dissonance etc. He should, ideally, just stand up to the Jewish lobby and appeal to the wider public, but in fact is now –again– cringing before the Jewish Zionists and “apologizing” to the bastards even as they try to get him removed! I see that as partly a tactic, however. If Corbyn retreats like the tide before the attacks, seems to give in at least verbally, then the Jews have nothing to press against. Judo? Sun-Tzu?
I never thought much of Corbyn, who had a very poor academic background, no real work background, no profession, as well as derivative and quite dull ideas. However, he is somehow likeable, and is a recognizable English type, the radical socialistic/anarchistic, cap-wearing Labourite of the last century, to be found in local Labour parties, on allotments, at steam fairs and heritage railway stations. More importantly, for me, Corbyn is not actually in the pocket of the Jewish Zionists, and (trump card) is laying the ground for social nationalism by just being there and being attacked by the Zionist cabal(s). If Corbyn can hang on in there as Labour leader, he stands a good chance of becoming Prime Minister within a year, even if only as head of a minority government.
Corbyn-Labour can lay the ground for social-nationalism. Many of his own supporters are, albeit unwittingly, halfway there. That is why the enemy are trying to topple him. I hope that they fail.
Update, 2 January 2024
Well, 5-6 years on, much water has passed under bridge. As we now know, the mendacious snake-oil salesman and (in reality, though not usually openly, and as “controlled opposition”) Israel mouthpiece, Nigel Farage, stabbed in the back his own supporters and candidates (and even, in effect, stole their money) by standing down the Brexit Party candidates at the 2019 General Election, thus gifting dozens of seats, maybe even 100 seats, to the Conservative Party. That is part of why the Con Party “won” that election.
The other reason why the Con Party “won” (though scarcely at all increasing its vote-percentage) was because Labour’s vote-percentage fell by, if I recall aright, about 8 points. The 4 years of ceaseless “Corbyn is a terrorist” propaganda had had its effect on the electorate.

2017 Labour voters voted with their feet in 2019; huge numbers abstained, some voted for the Con Party or elsewhere.
So here we are. The Israel-lobby in Labour grabbed power after Corbyn resigned. They selected dull-as-ditchwater Starmer (pro-Israel, Labour Friends of Israel member, Jewish lawyer wife, children being brought up as if fully-Jewish) as leader.
MPs and others who are anti-Israel etc have been purged; even Corbyn himself. It now looks as if Starmer-Labour will win the 2024 GE handsomely, but purely by default, because the Government of little Indian money-juggler Sunak is so incredibly useless..
