A senior union leader has attacked former Labour ministers for arguing that the party's general election manifesto was too left-wing.
Paul Kenny, general secretary of the GMB, said there should be no finger-pointing at unions for Labour's defeat, especially from those living in big houses, having paid directorships or being based in the House of Lords.
He told the GMB's annual conference in Dublin: "I have been absolutely sickened by the sight of old has-beens in the Labour Party lecturing us about the manifesto being too left-wing.
"They even suggest that the election was lost because the British people wanted a return to New Labour, and throw in attacks on trade unions for good measure. There we have the essence of why millions of trade unionists didn't vote Labour."
Mr Kenny said the party's critics should go back to the museums "they have crawled out of".
