It also produces a weekly newsletter, Look Left

The Oxford newspaper The Isis noted Lewis' leadership ability at this early stage in his career in their February 7, 1934 issue: "The energy of these University Socialists is almost unbelievable. If the Socialist movement as a whole is anything like as active as they are, then a socialist victory at the next election is inevitiable.
In February 1934, British fascist William Joyce, (Lord Haw Haw), visited Oxford. Lewis and future Ontario Co-operative Commonwealth Federation leader Ted Jolliffe, organised a noisy protest against the fascist, by simply planting Labour Club members, in the dance hall that Joyce was speaking in, and causing a commotion, as groups of two and three left making much noise on the creaking wooden floors. The speech was foiled. Afterwards, the Blackshirts contigient had a street battle in Oxford with members of the Labour Club and the townsfolk.
Lewis prevented the communists from really making inroads at Oxford during his time there. He increased the Labour Club's membership by three quarters, from 484 members in December 1932 to over 850 members by the time he left, while the October club never rose above 300 members. Ted Jolliffe stated "there was a difference between his speeches at the [[Oxford Union|[Oxford] Union]] and his speeches at the Labour Club. His speeches at th Union had more humour in them; the atmosphere was entirely different. But his speeches at the Labour Club were deadly serious.... His influence at the Labour Club, more than anyone else's, I think, explains the failure of the Communists to make headway there. In 1935, the Soviet controlled Comintern's Seventh Congress, called for a united left response to fascism, called the popular front. The communist October Club used this call, for a popular front, as a pretext to have a union between themselves and the Labour Club. Under Lewis' leadership, the club was able to easily defeat a motion by the October Club, as only 20 OULC members voted for the union.
When Lewis returned to Canada in the summer of 1935, there really wasn't anyone to replace him, to keep the communists at bay as The Isis noted: "The Labour may have rejected fusion [with the October Club] but the matter is not yet settled. An interesting thing is the dearth of what are technically known as 'promising people' in the ranks of the Labour Club. For years the Labour Club has been turning out a Geoffrey Wilson, a Frank Hardie, a John Cripps, a David Lewis, each year: but this [coming] year there seems to be no figures as outstanding as these.
The schism was extremely damaging to the OULC, which was quickly reduced to an increasingly extreme communist rump; within 12 months the OULC had fewer than 100 members. Its standing was further damaged when the national Labour Party chose to allow the OUDSC to affiliate to it — making the OUDSC the effective student Labour Party body in Oxford, ignoring the presence of OULC. The club's financial future was also in jeopardy, as new OUDSC Treasurer Roy Jenkins and OULC Treasurer Iris Murdoch engaged in an ongoing battle about which new organization should carry the debts and assets present prior to the split.
As the war progressed, membership of both clubs changed, and the reasons for the split became more the stuff of history, OULC and OUDSC merged following a referendum of the members of both clubs in 1943. It is interesting to note that many of the key protagonists of both clubs went on to be colleagues in future Labour governments. It is also of interest that Roy Jenkins in particular demonstrated a willingness to depart from established party organizations when his position would be better represented by a new, more moderate organisation. This foreshadowed the establishment of the Social Democratic Party over forty years later.
