Labour has suspended a councillor over social media posts, including a suggestion that Israel should be relocated to the United States.

Nottingham City councillor Ilyas Aziz, who also appeared to compare the actions of Israel against the Palestinians to those of the Nazis against the Jews, has been suspended pending an investigation in the latest row over controversial comments to hit the party.

The move comes after Jeremy Corbyn insisted the party is "united" in opposing anti-Semitism in the wake of a turbulent week which has also seen the suspension of MP Naz Shah and former London mayor Ken Livingstone.

A Labour spokeswoman said: " Ilyas Aziz has been suspended from the Labour Party pending an investigation."

Among Facebook posts from Mr Aziz's account highlighted on the Guido Fawkes website was a comment saying: "Jews and Muslims lived together in the Middle East, in peace pre 1948. Perhaps it would have been wiser to create Israel in America it's big enough. They could relocate even now."

Mr Aziz claimed he had not written the post from 2014, although it remained on his Facebook page.

The councillor reposted a series of comments and images on his Facebook page criticising Israel.

Posting a link to an article about Nazi Germany in 2014, he said: "A reminder of the treatment and suffering of Jews in Nazi Germany. ARE THERE ANY SIMILARITIES TO HOW ISRAEL IS TREATING PALESTINIANS."

Asked if he suggested Israel could be relocated and whether he feared he could be suspended as a result - as it was the same suggestion that led to the action against Ms Shah - he told the Press Association: "I didn't write that."

On the comparison with the Nazis, Mr Aziz said: "That one possibly (was) because you make a comparison that it's wrong, that nobody should be doing that."

Asked whether he thought that people who criticised Israeli policy faced being accused of anti-Semitism, he said: "I think you need to be careful.

"The thing you have got to try and appreciate is that if a particular government - whether it's the Israeli government, whether it's the British government - if the government is actually doing something wrong they should be criticised.

"But not the population itself, it's got nothing to do with them, it's got nothing to do with the religion."

He added that "as politicians you need to be careful" and said he supported the suspensions imposed on Ms Shah and Mr Livingstone "but at the same time I'm also a great believer that justice should be done and I think they should do a swift inquiry into exactly what the feelings are and if the party feels that they have crossed a boundary then yes, they should be suspended or expelled".

After his suspension had been announced Mr Aziz said: "I have no comment at all."

The speed with which Labour acted in Mr Aziz's case comes after opponents accused Mr Corbyn of responding too slowly to deal with incidents - most notably his ally Mr Livingstone's incendiary assertion, while defending Ms Shah, that Hitler was supporting Zionism before he "went mad and ended up killing six million Jews".

The Labour leader has announced an independent review and pledged to tighten party codes of conduct on anti-Semitism and other forms of racism in a bid to put a lid on the furore.

But he faced calls from Israeli politicians and diplomats to give a more "unequivocal" condemnation and warnings - including from the party's London mayoral candidate Sadiq Khan - that the party would be punished in the May 5 elections.

Allies of Mr Corbyn fought back over the weekend and warned critics they had no chance of ousting the leader.

Shadow cabinet minister Diane Abbott said it was "a smear to say that the Labour Party has a problem with anti-Semitism".

Mr Livingstone's comments linking Hitler with Zionism - for which he has declined to apologise in a string of media interviews - were "extremely offensive", she told BBC1's Andrew Marr Show, but not part of any wider pattern.

"Two hundred thousand people have joined the Labour Party. Are you saying that because there have been 12 reported incidents of hate speech online, that the Labour Party is somehow intrinsically anti-Semitic?"

She said she would be "dismayed if some people were hurling around accusations of anti-Semitism as part of some intra-Labour Party dispute".

Unite union leader Len McCluskey told the Guardian that Mr Corbyn's critics included some "treacherous" MPs who had been setting "traps" for the Labour leader.

The Times suggested that frontbenchers could resign within weeks in protest at Mr Corbyn's handling of the anti-Semitism row and the prospect of electoral setbacks on Thursday.

But former minister Iain Wright told BBC Radio 4's Today suggested there would be no move against Mr Corbyn in the "short term".

Asked if he would "live or die" by the results on Thursday, he said: "I think we will do well in London, in my constituency in Hartlepool we have got elections both in terms of the local council and police and crime commissioners - I hope we do well, the expectations are that we will.

"So I don't think that question arises in the immediate short term."
