1940–1941 In 1940, Lang seceded from Labor, along with several supporters, and formed a new party called the
Australian Labor Party (Non-Communist), in retaliation of a policy opposing Australian involvement in
World War II, adopted by the state executive. The breakaway party contested the
1940 federal election, but with only minority support in the Labor movement of NSW. Many of his old supporters such as
Eddie Ward remained loyal to
Australian Labor Party leader
John Curtin, and Lang candidates polled poorly. The Federal Executive again intervened in the NSW branch and expelled the leftist elements. Following the Federal intervention, prior to the
May 1941 state election, Lang and nearly all of his followers rejoined the ALP. The reunification would help assist Curtin to become
Prime Minister of Australia in October 1941, allowing Labor to form government.
1943–1950 In 1943, having published newspaper articles attacking McKell (NSW's Premier since 1941) and Prime Minister John Curtin, Lang was expelled from the ALP and restarted the Australian Labor Party (Non-Communist). This manifestation of Lang Labor contested the
1944 NSW election, electing two members—Lang and
Lilian Fowler, Australia's first female mayor. When Lang transferred to federal politics, he was succeeded as the Lang Labor member for
Auburn by his son
James. Although Fowler and Chris Lang were both re-elected in the
1947 NSW election, they were defeated in
1950, leading to the party essentially being defunct. During Lang's expulsion, the ALP continued to enjoy their greatest House of Representatives victory both in terms of proportion of seats and their strongest national two-party vote at the
1943 federal election and additionally their first successful federal re-election attempt at the
1946 federal election. During this election Lang was elected to the
House of Representatives for the federal seat of
Reid, being elected with the benefit of
Liberal Party preferences. Lang was a nuisance to the Labor government led, since 1945, by
Ben Chifley, whom he repeatedly castigated in public. He lost his seat at the
1949 election. In the
double dissolution 1951 election he stood for the
Senate, but was not elected. ==Aftermath==
