Ken Livingstone has blamed "embittered MPs" for branding him a Nazi apologist over his controversial comments about Hitler, which he said were "factual" and comparable to "1+1=2".

The Labour leader suspended Mr Livingstone in April after he invoked Hitler to defend a colleague over anti-Semitic remarks and claimed that there was a “well-orchestrated campaign” against the party by the “Israel lobby”.

His comments led to a face-to-face confrontation with John Mann, a Labour MP, who told Mr Livingstone on live television that he was a "disgrace" and a "Nazi apologist".
