The 1931 Liverpool East Toxteth by-election was held on 5 February 1931. The by-election was held due to the succession to the peerage of the incumbent Conservative MP, Henry Mond. It was won by the Conservative candidate Patrick Buchan-Hepburn. Mond, a former Liberal had won the seat for the Conservatives at a by-election in 1929 and had held it with an increased at the 1929 general election a few weeks later.[1] Buchan-Hepburn had previously served on the London County Council and as a private secretary to Winston Churchill.[2]
At the general election later in the year Patrick Buchan-Hepburn scored an even greater victory, defeating a Liberal by over 19,000 votes. On that occasion, Labour did not field a candidate.[2]
