'But there were no actions to go with the words, yet again, and that's why we thought the meeting has been a real missed opportunity and a great disappointment, ' he added. He thanked the organizations for "a positive and constructive meeting about tackling anti-Semitism" and said that he was "absolutely committed to rooting out anti-Semitism from our party and our society".
The leadership of the two groups met with Corbyn on Tuesday afternoon with hopes that the afternoon's meeting would be a productive one.
After the meeting, spokespeople for the two Jewish groups told reporters they were surprised at the lack of action, saying Corbyn's team had known about their specific demands for some time.
"For us, that is frustrating", a JLC spokesman said.
"Many of those issues we agreed to implement, or we were already implementing - or we agreed to consider them in more detail". He expressed surprise that Corbyn and Formby could not agree to adopting the IHRA definition of antisemitism, calling it "quite an easy thing for them to have said yes to". He repeated in the main points of his Evening Standard apology and concluded by promising to "lay out the further steps we are taking in the coming weeks", and that his party "will not fail our Jewish brothers and sisters". "This isn't asking for a lot, that as a community we ask for the protection and support of the leadership of the party".
A fresh row over the issue exploded last month after a Facebook post by Mr Corbyn resurfaced in which he appeared to defend an anti-Semitic mural.
"We were not promised any of the things that we said were necessary to remedy the problem".
Writing in the London Evening Standard, Corbyn described anti-Semitism as a "poison that must be challenged wherever it raises its head" and admitted that while Labour has "a long and proud record of standing against anti-Semitism", the party "must also face the uncomfortable fact that a small number of our members and supporters hold anti-Semitic views and attitudes, which need to be confronted and dealt with more rapidly and effectively".
Several high-profile Labour MPs have rallied around colleague Ruth Smeeth ahead of a hearing investigating alleged anti-Semitism.
Wadsworth's case will be heard by Labour's national constitutional committee, a quasi-judicial body that has the power to expel members from the party.
Labour MP Ian Austin wrote on Twitter following the meeting: "How could Labour leadership watch unprecedented protest by Jewish community and last week's debate and still fail to deal with their concerns?" A decision is expected on Thursday.
