1919 Liverpool West Derby by-election

Vacancy

The seat had become vacant on the elevation to the peerage of the constituency's Unionist Member of Parliament (MP), F. E. Smith, as Baron Birkenhead. He had been raised to the peerage to take up the post of Lord Chancellor.

Smith had held the seat since the 1918 general election, when he was endorsed by the Coalition Government. Before that he held its predecessor seat, Liverpool Walton since the 1906 general election.

The Unionist Party selected as its candidate Rear-Admiral Sir William Reginald Hall. Hall was endorsed by the Coalition Government.
George Nelson stood for the Labour Party. He had stood against Smith at the recent General Election.

Turnout was unsurprisingly low so soon after a General Election. Hall won the seat by a much reduced margin.
