"Mr Corbyn, a longstanding ally of the former London mayor, said: "Ken Livingstone's comments have been grossly insensitive, and he has caused deep offence and hurt to the Jewish community.
"Labour's independently elected National Constitutional Committee has found Ken guilty of bringing the party into disrepute and suspended him for two years.
"It is deeply disappointing that, despite his long record of standing up to racism, Ken has failed to acknowledge or apologise for the hurt he has caused. Many people are understandably upset that he has continued to make offensive remarks which could open him to further disciplinary action."

"Labour deputy leader Tom Watson said it was "incomprehensible" Mr Livingstone had not been expelled, while former leader Ed Miliband said he was "appalled" at the lack of remorse being shown.
Mr Watson said the ex-London mayor's behaviour "discredits the party I love... I am ashamed that we have allowed Mr Livingstone to cause such distress. This shames us all, and I'm deeply saddened by it."
Shadow attorney general Baroness Chakrabarti, who led an inquiry into claims of anti-Semitism in Labour, said she was "horrified" by the way Mr Livingstone had behaved"
