"The ... analysis points to a culture within the party which,at best,did not do enough to prevent anti-Semitism and,at worst,could be seen to accept it,"the EHRC said.
Corbyn's successor,Keir Starmer,said he accepted the findings in full and would implement all the recommended reforms.
"It is a day of shame for the Labour Party. We have failed Jewish people[...] I am truly sorry for all the pain and grief that has been caused,"he said.
"Never again will we fail to tackle anti-Semitism and never again will we lose your trust."
Starmer has been trying to mark a clean break from the Corbyn era on the anti-Semitism issue,but the ruling Conservatives were quick to point out that he had held a senior post as Labour Brexit policy chief under Corbyn.
Corbyn,71,said he did not accept all the EHRC findings,that the scale of the problem had been overstated by the media and by his political opponents,and that his attempts to deal with the issue had been blocked by"obstructive party bureaucracy".
