Janner campaigned in opposition to the government's policy on Palestine. On 20 October 1930, the Labour government's Passfield white paper was issued, which proposed the introduction of severe restrictions on Jewish immigration to Palestine. This went down particularly well in the Whitechapel area of the constituency. The TGWU were worried that the Labour candidate would lose Jewish support and the seat because of the government's white paper. The Union's Secretary, Ernest Bevin met with Dov Hoz and the visiting Jewish Labour movement in Palestine, the Poale Zion, who were unhappy about the government's proposals. He persuaded them to publicly back the Labour candidate, which put them in conflict with many members of the British Poale Zion. Dov Hoz agreed to share a platform with Bevin and Hall at a Labour campaign rally. At the meeting, following the speech from Bevin, Hoz got up to speak and was howled down by the audience. The meeting became so disrupted that the police were called in to restore order. Hoz accused the Liberal candidate Janner, of exploiting the white paper for his own political ends. Despite a massive swing to the Liberals, Hall held onto the seat on a much reduced majority;  Hall blamed the fall in the Labour vote on the economic difficulties faced by the Labour Government, and on a "flood of misrepresentation" from the government's opponents. Hall held the seat until Janner took it for the Liberals at the 1931 election. Guinness was elected MP for Bath at the same elections;
