The 1911 Bootle by-election was a by-election held for the British House of Commons constituency of Bootle in Merseyside on 27 March 1911. It was won by the Conservative Party candidate Bonar Law.

Vacancy

The seat had become vacant on 13 March 1911 when the sitting Conservative Member of Parliament (MP), 73-year-old Thomas Myles Sandys had resigned from the House of Commons by the procedural device of accepting the office of Steward of the Manor of Northstead, a notional 'office of profit under the crown'. He had held the seat since the 1885 general election, and died on 18 October 1911.

Result

The result was a victory for the Conservative candidate, Bonar Law, who won the seat with 56% of the votes.

Bonar Law was later elected Leader of the Conservative Party in the House of Commons, and went on to hold a series of ministerial positions before becoming Prime Minister for seven months from 1922 to 1923
