Spoor had planned to retire at the next general election, and the Bishop Auckland
Constituency Labour Party had selected
Hugh Dalton as its
prospective parliamentary candidate. However, Dalton was already MP for the then-marginal
Peckham constituency in
South London, and had sought a
safer seat. He would have had to resign his Peckham seat to stand in Bishop Auckland. To add to the complications, even if he had been minded to do that, a further complication was that the prospective Labour candidate for Peckham was
John Beckett, the sitting MP for
Gateshead. To avoid triggering two further by-elections, a Labour candidate was needed who would agree to stand down at the next general election. The seventy members of Bishop Auckland
Constituency Labour Party's general committee unanimously chose Hugh Dalton's wife
Ruth, because she could be relied on to resign in favour of her husband as soon as Parliament was dissolved; no other candidate was even considered. The
Liberal Party candidate was
Aaron Curry, who had contested
Houghton-le-Spring at the
1923 and
1924 general elections, and who had also been unsuccessful at the
Wallsend by-election in 1926. The
Conservative Party, which had not contested Bishop Auckland in 1924, selected as its candidate H. Thompson, who had not previously contested a Parliamentary election. == Result ==
