MacMaster Unionist Richardson Unionist The 1922 Chertsey by-election was a parliamentary by-election for the British House of Commons constituency of Chertsey on 24 March 1922.

The by-election was caused by the death of the sitting Unionist MP, Sir Donald Macmaster on 3 March 1922.

Chertsey had returned Conservative or Unionist candidates at every election since the constituency was created in 1885, apart from the Liberal landslide of 1906.

The result at the last general election was: The Unionists held onto the seat with a greatly reduced majority.

The Liberal Party never managed to mount as strong a challenge again as Chertsey remained a safe Conservative seat throughout its history.
