Hellywelly 4,
Naz Shah was suspended when an old Facebook post from before she was an MP was published by a Conservative blogger. Here it is (Hope the link works).

It has been called anti semitic. It is clearly a comment on the State of Israel, and the cost to the American taxpayer of Israel. But it does not attack anyone for being jewish. It does not say this is a stated aim, or any Israelis should be forced to move. It is meant as a jokey solution to the Israel / Palestinian problem, not a manifesto. The graphic stand alone is not anti semitic. It is anti the State of Israel in its present location.
Shah's own comment is rather dumb, as she confuses US Dollars with Pounds Sterling and that gives the false impression that UK citizens are paying 3 billion, not US citizens. Her comment of 'Problem solved' is not anti semitic, as the graphic itself is not anti semitic.
It is legitimate to question Israel as a foreign country, particularly if some of Israels actions are contrary to your own idiology. Unfortunately the pro Israel lobby jump on any criticism of the country, and particularly on its foreign polucy toward the Palestinians, as anti Jewish and therefore anti semitic. This is a deliberate mistake intended to stiffle debate and deflect any criticism.
So why has this become news?
The Labour leadership election unnanously selected Corbyn as leader. It was a huge rejection of New Labour and all it stood for. Unfortunately, many of the sitting MPs are Blairite New Labour followers. They are in open revolt of their leader and seek to discredit him. One way (there are others) is to portray him as anti semitic, because he has supported the Palestinians in the past. So we have suddenly seen several Labour anti semitism stories pop up in the media. The aim of them all is to discredit Corbyn.
One of those Blairite MPs seeking to remove Corbyn is John Mann. John Mann is also very pro Israel and is chairman of the All-Party Parliamentary Group against Antisemitism. He confronted Livingstone outside the BBC over comments he had made about the Nazis supporting a Jewish state. Whilst that is true, I am unsure of the context that Livingstone reminded us of the fact. Anyhow, it was a red rag (lirerally) to the pro Israel lobby, who as usual shout 'anti semitism!' At any criticism of Israel the country. Hence the confrontation between Johm Mann (who has got reprimanded) and Ken Livingstone (who has been suspended).
