The 1921 Woolwich East by-election was a parliamentary by-election held on 2 March 1921 for the British House of Commons constituency of Woolwich East, in the Metropolitan Borough of Woolwich in London.
Vacancy.
The seat had become vacant on the resignation of the constituency's Labour Member of Parliament (MP), Will Crooks, due to ill-health. Crooks was a noted trade unionist and working-class organiser, and had represented Woolwich East and its predecessor seat, Woolwich, since a by-election in 1903, with a gap between the two general elections of 1910.
Aftermath.
Gee held the seat until the 1922 election, when Harry Snell retook the seat for Labour.
